   SINEX -   Solution (Software/technique) INdependent EXchange Format 
                      Version 1.00 (June 30, 1996)

    INTRODUCTION

    The SINEX acronym was suggested by Blewitt et al. (1994) and the first
    versions,  0.04, 0.05 and 1.00 evolved from the work and contributions of
    the SINEX Working Group (WG)  chaired by G. Blewitt.  The other SINEX WG
    members consisted of Claude Boucher, Yehuda Bock, Jeff Freymueller, Gerd
    Gendt, Werner Gurtner, Mike Heflin and Jan Kouba. Also contributions of Z.
    Altamimi, T. Herring, Phil Davies, Remi Ferland, David Hutchison and other
    IGS AC colleagues are noted and acknowledged here, in particular all the
    ACs submitting and using SINEX(0.05) every week since mid 1995, as a part
    of the IGS ITRF densification pilot project. 

    SINEX was designed to be modular and general enough to handle GPS as well
    as other techniques.  In particular the information on hardware (receiver,
    antenna),  occupancy and various correspondence between hardware, solution
    and input  files can be preserved, which is essential for any serious
    analysis and interpretation of GPS results. It preserves input/output
    compatibility so that output SINEX files can be used (latter on) as input
    into subsequent computation/solutions. It also provides complete
    information  on apriori information so that it can be removed whenever
    required,  making it unnecessary to submit or distribute multiple (SINEX)
    solution files, e.g. constrained and unconstrained (free) solution files.

    CHANGES FROM VERSION 0.05 TO 1.00
    
    The version 0.05 has undergone some "fine tuning" as the result of the IGS
    ITRF densification pilot project but it is yet to be proof tested by other
    techniques. More specifically the following is a summary of the changes and
    enhancements from the previous version 0.05 to the new version 1.00:
    
    1) Backward compatibility with the version 0.05 is assured my the version #,
    which MUST be coded on the first line.

    2) Strictly fixed format, all fields are now specified and described in
    details in the Appendix I. In most cases the format fields are the same as
    in the version 0.05 with some notable exceptions. For crucial fileds such
    as SOLUTION/ESTIMATE and SOLUTION/MATRIX a generous field length of 21 is
    specified which should be sufficient for up to 16 significant digits;
    furthermore the field lengths for receiver and antenna types in the
    SITE/RECEIVER and SITE/ANTENNA blocks were increased from 16 to 20 chars to
    make them compatible with RINEX. Also strict adherence to IGS
    receiver/antenna code names is now required (see the Appendix III for the
    list of the IGS receiver/antenna standard names).

    3) The version 1.00 accommodates the CORR matrix type in a different
    fashion, namely when the CORR matrix type is used in the SOLUTION/MATRIX
    blocks it is now required that standard deviations (STDs) are coded on the
    main diagonal, in place of 1.000's. This way the STDs in the CORR
    matrix could be given to the full precision and they take precedent over
    any STDs in the SOLUTION/ESTIMATE & SOLUTION/APRIORI blocks which may not
    be given to a sufficient precision. The other matrix form (e.g. COVA) is
    still valid and acceptable. 

    4) A new (mandatory for IGS) block  (SOLUTION/STATISTICS) is introduced for
    needed solution statistics (see the example below)
    
+SOLUTION/STATISTICS
*_STATISTICAL PARAMETER________ __VALUE(S)____________
 VARIANCE FACTOR                0.9260149874E-02
 NUMBER OF OBSERVATIONS         811865           
 NUMBER OF UNKNOWNS             22142
 SAMPLING INTERVAL(SECONDS)      120
-SOLUTION/STATISTICS
    
    Other possible headings/entries might include e.g.:
    SQUARE SUM RESIDUALS (VTPV)
    NUMBER OF DEGREES OF FREEDOM , etc.
    
    5) Additional standardized parameter code names were introduced to
    accommodate some specific users, more parameter codes may be introduced as
    the need arises. For future applications and to ease  interpretation, the
    parameter code fields have been increased from four to six chars in all the
    relevant (SOLUTION) blocks, with some minor changes in the format fields to
    accommodate this change. It is suggested that the the current (four chars)
    codes used by IGS (STAX, STAY, STAZ, VELY, VELY, VELZ, LOD, UT, XPO, YPO)
    are retained  for compatibility/continuity reasons and that any new ones
    take the advantage of the six chars field. E.g. for the orbit parameters
    the following code names could be suggested:


    SAT__X PR01   X state of PRN 01
    SAT__Y PR01   Y  "       "
    SAT__Z PR01   Z  "       "
    
    SAT_VX PR01   Vx "       "
    .
    .
    SAT_RP PR01   Rp scale of PRN 01
    SAT_GX PR01   Gx   "       "
    SAT_GZ PR01   Gz   "       "
    SATYBI PR01   Gy  bias     "
    
    TROTOT ALGO   Tropo delay (wet + dry) at ALGO
    TRODRY ALGO   Tropo delay (dry)
    TROWET ALGO   Tropo delay (wet)

    etc.

    Note: The use of SV rather PR could be considered here, as it is more
    meaningful, but since the GPS users are accustomed to PRN's (and PRNs are
    used in sp3) we may not have any other choice. Considering that "P" is used
    by IERS as the technique code for GPS, it may not be (i.e. "PR") such a bad
    choice. Other satellite system would then have to be assigned unique code
    of two chars.

    6) The version 1.00 discontinues the practice of using separate OCC_ and
    SOLN codes in the SITE and SOLUTION blocks, respectively, as it serves 
    no useful purpose. Further more it is suggested to use the SOLN codes for
    the SITE blocks as well (i.e. SITE/ECCENTRICITY, ./RECEIVER; ./ANTENNA and
    ./DATA). In most cases for the individual AC SINEXes, the SOLN codes should
    then be coded with the default characters "-" which could mean that "this
    record applies to all estimates" (note  SITE+PT+SOLN defines a unique
    estimate, SITE+PT is equivalent to DOMES (DOMEX)and uniquely identifies a
    geodetic mark). What is exactly meant should be clear from the examples
    below:


+SITE/ANTENNA
*Code PT SOLN T _Data Start_ __Data End__ __antenna type______ _S/N_
* lines removed
 GOLD  A ---- P 92:180:00000 95:304:79200 DORNE MARGOLIN R        95
 GOLD  A ---- P 95:304:79200 00:000:00000 DORNE MARGOLIN T     -----
* etc
*   (NOTE: above ANTENNA TYPE FIELD = 20chars)
 .
       
+SITE/ECCENTRICITY
*Code PT SOLN T _Data Start_ __Data End__ typ __ARP-benchmark (m)_______
* lines removed
 GOLD  A ---- P 92:180:00000 95:304:79200 UNE    .0000    .0000    .0000
 GOLD  A ---- P 95:304:79200 00:000:00000 UNE    .0025    .0000    .0000
* etc
* NOTE: Continuity of multiple entry of a site must be adhered, i.e. the
*    end epoch of the first ( must be coded) =< the start epoch of the second
*    entry. 
 .
  
    This would allow only one (e.g. SOLN=1) for GOLD in the ESTIMATE blocks. On
    the other hand if one prefers two SOLNs (e.g. 1 & 2) for GOLD in the
    ESTIMATE blocks, e.g. before and after an antenna change, then the same
    (e.g. 1 & 2) SOLN must be used in all GOLD entries in the SITE blocks as
    well. Conversely when two solutions (SOLN 1, 2) are introduced for some
    reasons other than instrument/antenna change (e.g. as a result a coseismic
    change, with the same rec/antenna/eccentricity) then, only one entry in the
    SITE blocks with the default character codes ("-") in the SOLN filed need
    to be coded or alternatively two identical entries with 1 and 2 in the SOLN
    field could be used (except, of course, for the start and end epochs which
    must be continuous and non overlapping).  This considerably  enhances the
    SINEX effectiveness. 

    SINEX SYNTAX

    SINEX is an ASCII file with lines of 80chars or less. It consists  of a
    number of blocks which are mutually referenced (related) through station
    codes/names, epochs and/or index counters. Some blocks consist of
    descriptive lines (starting in Col.2) and/or fixed format fields with
    numerous headers and descriptive annotations. 

    The first line is MANDATORY and must start with "%" in col 1, and  contains
    information about the  agency, file identification, solution spans,
    techniques, type of solution, etc. (for more details see the Appendix I or
     II). The last line ends with "%ENDSNX". 

    The SINEX format consists of a number BLOCKS  which start with "+" in the
    first col. followed by a standardized block  labels, and each block ends
    with  "-" and the block label. Each block data starts in the column 2 or
    higher.  Blocks can be in any order, provided that they start with (+) and
    end with (-) block labels.  The first header line and most blocks are
    related through epochs or  time stamps in the following format:
    YY:DOY:SECOD  YY-year; DOY- day of year; SECOD -sec of day;
    E.g. the epoch 95:120:86399  denotes April 30, 1995 (23:59:59UT). The
    epochs  00:00:00000 are allowed in all blocks (except the first header
    line) and  default into the start or end epochs of the first header line
    which must always  be coded. This is particularly useful for some blocks,
    such as the ones  related to hardware, occupancy, which should be centrally
    archived by IGSCB  with 00:00:00000 as the end (current) epochs, and which
    should be readily  usable by ACs for SINEX and other analysis/processing as
    official  (authoritative) IGS information.

    COMMENT lines starts with "*" in Col. 1 and can be anywhere within or
    outside  a block, though for the clarity sake, beginning and ends of blocks
    are preferable.  For increased portability, the floating number exponent of
    "E" should be used  rather than "D" or "d" which is not recognized by some
    compiler/installations.  Fields not coded should be filled with "-"
    characters to  allow efficient row and column format readings.

    The most important blocks are the SOLUTION blocks. They are in fixed format
    and have been adopted and used by IERS (ISEF1) submission format as well.
    (For more information on the format, see the Appendix I). Only two SOLUTION
    blocks (SOLUTION/ESTIMATE and SOLUTION/MATRIX_ESTIMATE) are MANDATORY and
    must  be coded. They contain complete solutions (apriori + solution vector)
    and the corresponding standard deviations, and the corresponding matrix.
    Although various matrix forms are allowed in SINEX (as specified by a
    matrix type code),  triangular correlation matrix (e.g.
    SOLUTION/MATRIX_ESTIMATE L CORR) is preferred and  recommended for IGS
    since it is easier to visualize. Important but not mandatory (though
    RECOMMENDED for IGS purposes) are the next two blocks, i.e. the
    SOLUTION/APRIORI and SOLUTION/MATRIX_APRIORI. The  scale of estimated and
    apriori standard deviations can, in principle, be  arbitrary (note even
    apriori scaling is arbitrary, depending on the observation  weighting).
    However, both estimated and apriori standard deviations (and the
    corresponding matrices) MUST use the same scaling (i.e. variance) factor. 
    Otherwise the apriori information cannot be be  rigorously removed to form 
    free solutions (e.g. normal matrices). Scaling between different SINEX 
    solutions is beyond the SINEX format and must be dealt with at the 
    combination/analysis stage.

1. Introduction
 
 This document describes the Software Independent Exchange (SINEX) format. The 
need for such a format grew out of the increasing need to exchange 
station coordinates information. It started in early 1995 by an effort from 
a number of IGS participants. The format has quickly evolved beyond the 
original objectives. The information is organized by blocks. The format is 
designed to be easily extended as need may arise.

 
2. Data Structure
 
 Each SINEX line has at most 80 ASCII characters.
The SINEX file is subdivided in groups of data called blocks. Each block is 
enclosed by a header and trailer line. Each block has a fixed format. The 
blocks contain information on the file, its input, the sites and the solution. 
All elements within a line are defined. A character field without information 
will have "-"s within its field and a missing numerical element will have a 
value of 0 within its field. This lets the SINEX file to be accessible 
"column-wise" as well as "line-wise". Character fields should be left hand
justified whenever applicable.
 
 The first character of each line identify the type of information that the 
line contains. Five characters are reserved. They have the following 
meaning when they are at the beginning of a line, they identify:
 Character	Definition
 "%"            Header and trailer line,
 "*"            Comment line within the header and trailer line,
 "+"            Title at the start of a block
 "-"            Title at the end of a block
 " "            Data line within a block

 No other character is allowed at the beginning of a line.
 
 A SINEX file must start with a Header line and ends with a footer line.
 
 The following blocks are defined:
 
 FILE/FERERENCE
 FILE/COMMENT
 INPUT/HISTORY
 INPUT/FILES
 INPUT/ACKNOWLEDGEMENTS
 SITE/ID
 SITE/DATA
 SITE/RECEIVER
 SITE/ANTENNA
 SITE/GPS_PHASE_CENTER
 SITE/ECCENTRICITY
 SOLUTION/EPOCH
 SOLUTION/STATISTICS
 SOLUTION/ESTIMATE
 SOLUTION/APRIORI
 SOLUTION/MATRIX_ESTIMATE {p} {type}
 SOLUTION/MATRIX_APRIORI  {p} {type}
 
	Where:	{p}     L or U
		{type}  CORR or COVA or INFO or SRIF
 
These block titles are immediately preceded by a "+" or a "-" as 
they mark the beginning or the end of a block. The block titles  must be in
capital letters. After a block has started(+) it must be ended(-) before another
block can begin. The general structure is as follow:

%=SNX........... (Header line)----------|
.............                           |
+(BLOCK TITLE)-------------|            |
 ............              |            |
 ............              |            |
 ............              |            |
-(BLOCK TITLE)-------------|            |
.............                           |
+(BLOCK TITLE)-------------|            |
 ............              |            |
 ............              |            |
 ............              |            |
-(BLOCK TITLE)------------ |            |
.............                           |
%ENDSNX          (Trailer line)---------|

 
Most fields within a SINEX line are separated by a single space. In the 
following sections, each SINEX line is defined by its field name, a general 
description and the (FORTRAN) format.

The comment line (not to be confused with the FILE/COMMENT Block) can be written
anywhere within the header and the footer line is defined as:
 
	 ___________________________________________________________________
	|______________________C_O_M_M_E_N_T___D_A_T_A___L_I_N_E____________|
	|                |                                   |              |
	|__Field_________|______Description__________________|___Format_____|
	|                |                                   |              |
	| Comment        | Any general comment relevant to   |   1H*,A79    |
	|                | the SINEX file.                   |              |
	|________________|___________________________________|______________|
                                                             |              |
                                                             |      80      |
                                                             |______________|
 
For example, the use of "*" in the first column can be used to effectively hide
information from the software without deleting it from the file.

 Some fields are found in several blocks. To keep the description short, they 
are described in detail here, and will be referred to in the sections with 
additional information added when necessary. The fields defined below will be 
referenced to by putting them within square brackets [] when encountered in the 
following sections.

19. SOLUTION/MATRIX_ESTIMATE Block (Mandatory)

 Description:
 
 The Estimate Matrix can be stored in an Upper or Lower triangular form. Only
 the Upper or Lower portion needs to be stored because the matrix is always
 symmetrical.
 The matrix contents can be:
 CORR	- Correlation Matrix
 COVA	- Covariance Matrix
 INFO	- Information Matrix (of Normals)
 SRIF	- Square Root Information Filter Matrix
 The distinction between the form and its contents is given by the title block
 which must take one of the following form:

 SOLUTION/MATRIX_ESTIMATE L CORR
 SOLUTION/MATRIX_ESTIMATE U CORR
 SOLUTION/MATRIX_ESTIMATE L COVA
 SOLUTION/MATRIX_ESTIMATE U COVA
 SOLUTION/MATRIX_ESTIMATE L INFO

 The Matrix Estimate Row/Column Number correspond to the Estimated Parameters 
 Index in the SOLUTION/ESTIMATE block. If the CORR
 matrix is used, standard deviations must be stored in the diagonal elements.
 Missing elements in the matrix are assumed to be zero (0); consequently, zero
 elements may be omitted. 

 NOTE: The same scale (variance) factor MUST be used for both MATRIX_ESTIMATE
 and MATRIX_APRIORI, as well as for the standard deviations in the ESTIMATE
 and APRIORI Blocks.



20. SOLUTION/MATRIX_APRIORI Block (Recommended/Mandatory)
 
 Description:
 
 The Apriori Matrix can be stored in an Upper or Lower triangular form. Only
 the Upper or Lower portion needs to be stored because the matrix is always
 symmetrical. Mandatory if any significant constraint have been applied to the 
 SOLUTION/ESTIMATE.
 The matrix contents can be:
 CORR	- Correlation Matrix
 COVA	- Covariance Matrix
 INFO	- Information Matrix (of Normals)
 SRIF	- Square Root Information Filter Martix
 The distinction between the form and its contents is given by the title block
 which must take one of the following form:

 SOLUTION/MATRIX_APRIORI L CORR
 SOLUTION/MATRIX_APRIORI U CORR
 SOLUTION/MATRIX_APRIORI L COVA
 SOLUTION/MATRIX_APRIORI U COVA
 SOLUTION/MATRIX_APRIORI L INFO
 SOLUTION/MATRIX_APRIORI U INFO
 SOLUTION/MATRIX_APRIORI L SRIF
 SOLUTION/MATRIX_APRIORI U SRIF

 Comment:

 The Matrix Apriori Row/Column Number correspond to the Apriori Parameters Index
 in the SOLUTION/APRIORI block. If the apriori constraint matrix is diagonal and
 no loss of significant digits occurs by using the Parameter Standard Deviation
 in the SOLUTION/APRIORI block, then, this block becomes redundant. If the CORR
 matrix is used, Standard deviations must be stored in the diagonal elements.
 Missing elements in the matrix are assumed to be zero (0); consequently, zero
 elements may be omitted. 

 NOTE: The same scale (variance) factor MUST be used for both MATRIX_ESTIMATE
 and MATRIX_APRIORI, as well as for the standard deviations in the ESTIMATE
 and APRIORI Blocks.

*-------------------------------------------------------------------------------
*
* This is an annotated SINEX example, based on the first submission from
* NRC. It has been amended and extended by NCL to illustrate the full
* SINEX 1.00 format. Long blocks have been truncated.
*

*   The following convention is followed for start and end date:
*    A start date of 00:000:00000 represents "since the beginning"
*    An end date of 00:000:00000 represents "up to now"
*  ***WARNING: NO overlapping epochs allowed, i.e. epochs referring to the
*  ***         same site must be continuous   *****
* 
*       Constraints code S are determined as follows:
*       (Note this is only SUGGESTION, common sense should be used here)
*       ratio   = ( apriori std. dev. ) / ( estimated std. dev. )
*
*                       ratio   < sqrt( 2 )     code S = 0 (fixed/constrained)
*       sqrt( 2 ) =<    ratio   < 10            code S = 1 (significant constr.)
*            10   =<    ratio                   code S = 2 (loose or unconstr. )
*
*    WARNING: This has not yet been standardized by IGS.
*
* 
*
*  EOP parameter types:
*               SINEX   Units                          
*               XPO     mas     (milli-arc seconds)    pole x 
*               YPO     mas     (milli-arc seconds)         y 
*               XPOR    ma/s    (milli-arc seconds/s)  pole x rate 
*               YPOR    ma/s    (milli-arc seconds/s)       y rate 
*               UT      ms      (milli-seconds)        UT1-UTC
*               LOD     ms      (milli-seconds)        Length of day
*
*       They are put at the end of the APRIORI and ESTIMATE blocks such they
*       can be removed easily.
*
*   In floating-point fields, the E symbol should be used for exponent -
*    other symbols (such as D) are not interpreted correctly by some
*    software (e.g. the ANSI C I/O library).
*
*   Fields should not be left blank if data is not applicable or
*    unavailable. These fields should be filled with a data-not-given
*    character '-' is used here. This enables the file to be read either
*    by column positions of fields, or by tokenising lines by whitespace.
*
* Block order should be kept consistent to aid readability. The format
* allows any blocks to be omitted, though obviously some are essential for
* solution submission, and the inclusion of all blocks is encouraged.
*
* Note the relational problem annotated in SITE/ANTENNA.
*
* The first and last lines begin '%'. Only '%', '*', '+', '-' and ' ' are
* allowed in the first column, meaning 'begin/end SINEX', 'comment',
* 'start block', 'end block' and 'data line' respectively.
*
* Header line explanation:
*
* '='                   Solution operator code. '=' means 'resultant' and is the
*                       only legal code in a header line. See INPUT/HISTORY
*                       notes.
* 'SNX'                 This is a SINEX document. Other formats may use similar
*                       headers.
* '1.00'                SINEX version number. MUST be coded. It is used for
*                       backward compatibity whenever required.
* 'NRC 95:122:67080'    The SINEX reference for this file. SINEX files are
*                       referred to by the three-character agency code, and a
*                       creation time-stamp in yy:ddd:sssss format. Agency codes
*                       should have entries in INPUT/ACKNOWLEDGEMENTS.

*         95:120:00000' The agency responsible for the data, and the overall
*                       data time span. 'COM' means multiple agencies.

* input solution - both are given here. Stations which are estimated in
* multiple input files have several lines here.
* The information here is fictional, to illustrate the format.
* Each station is defined in SOLUTION/EPOCHS, and each file (AGY+TIME_STAMP__)

* The parameter estimates are written here. Parameter types STAX, STAY, STAZ,
* VELX, VELY, VELZ (coordinate and velocity x, y, z) are followed by a
* station reference. Erp types LOD, UT, XPO, YPO have no station. The
* constraint code (0, 1 or 2) is given here for each parameter - the empty
* fields are filled with a data-not-given character (-)
*
*                 *** New to version 1.00 ***
*    TYPE increaded to 6 chars, ESTIMATED Value field to 21 chars, STD
*    decreased to 11chars (included here for information only) ***
*    The STDs for consistency must be the same as the corresponding values
*    derived from the MATRIX blocks, which are given to full num. precision.

There are THREE valid ways of coding a mid-week station
receiver/antenna change in weekly Sinex v1.00. To demonstrate this 
a recent change at GRAZ (week 0859) to show them below. To quote
Sinex v1.00 definition "SITE+PT+SOLN defines a unique estimate,
SITE+PT is equivalent to DOMES (DOMEX) and uniquely identifies a
geodetic mark".


Case (i): To state two separate estimates at a site, assuming the 
mark has changed. We call these marks GRAZ A and GRAZ B, and don't re-use
the old DOMES code, but code the second estimate with unknown DOMES:

+SITE/ID
 GRAZ  A 11001M002 P GRAZ                    15 29 36.5  47  4  1.7   538.3
 GRAZ  B --------- P GRAZ                    15 29 36.5  47  4  1.7   538.3
-SITE/ID
+SITE/RECEIVER
 GRAZ  A ---- P 96:174:00000 96:176:86369 ROGUE SNR-8C         ----- -----------
 GRAZ  B ---- P 96:177:00000 96:182:86369 ROGUE SNR-8000       ----- -----------
-SITE/RECEIVER
+SITE/ANTENNA
 GRAZ  A ---- P 96:174:00000 96:176:86369 DORNE MARGOLIN B       128
 GRAZ  B ---- P 96:177:00000 96:182:86369 DORNE MARGOLIN T       457
-SITE/ANTENNA
+SITE/ECCENTRICITY
 GRAZ  A ---- P 96:174:00000 96:176:86369 UNE   2.0680   0.0000   0.0000
 GRAZ  B ---- P 96:177:00000 96:182:86369 UNE   1.9640   0.0000   0.0000
-SITE/ECCENTRICITY
+SOLUTION/EPOCHS
 GRAZ  A    1 P 96:174:00000 96:176:86369 96:175:43185
 GRAZ  B    1 P 96:177:00000 96:182:86369 96:179:86385
-SOLUTION/EPOCHS

It is illegal to give GRAZ B the same DOMES as GRAZ A (see quote 
above).

Case (ii) To state two separate estimates at a site, reduced to a 
common mark. These are called GRAZ A 1 and GRAZ A 2, and both use 
a single SITE/ID line because there's only one mark:

+SITE/ID
 GRAZ  A 11001M002 P GRAZ                    15 29 36.5  47  4  1.7   538.3
-SITE/ID
+SITE/RECEIVER
 GRAZ  A 0001 P 96:174:00000 96:176:86369 ROGUE SNR-8C         ----- -----------
 GRAZ  A 0002 P 96:177:00000 96:182:86369 ROGUE SNR-8000       ----- -----------
-SITE/RECEIVER
+SITE/ANTENNA
 GRAZ  A 0001 P 96:174:00000 96:176:86369 DORNE MARGOLIN B       128
 GRAZ  A 0002 P 96:177:00000 96:182:86369 DORNE MARGOLIN T       457
-SITE/ANTENNA
+SITE/ECCENTRICITY
 GRAZ  A 0001 P 96:174:00000 96:176:86369 UNE   2.0680   0.0000   0.0000
 GRAZ  A 0002 P 96:177:00000 96:182:86369 UNE   1.9640   0.0000   0.0000
-SITE/ECCENTRICITY
+SOLUTION/EPOCHS
 GRAZ  A 0001 P 96:174:00000 96:176:86369 96:175:43185
 GRAZ  A 0002 P 96:177:00000 96:182:86369 96:179:86385
-SOLUTION/EPOCHS


Case (iii) To state a single estimate at a site, where the station
information changed during the data span. In this case there should
be only one SOLUTION/EPOCHS entry, for GRAZ A 1. As many SITE/...
entries may be used as required, in this example we need two in each
block.

+SITE/ID
 GRAZ  A 11001M002 P GRAZ                    15 29 36.5  47  4  1.7   538.3
-SITE/ID
+SITE/RECEIVER
 GRAZ  A ---- P 96:174:00000 96:176:86369 ROGUE SNR-8C         ----- -----------
 GRAZ  A ---- P 96:177:00000 96:182:86369 ROGUE SNR-8000       ----- -----------
-SITE/RECEIVER
+SITE/ANTENNA
 GRAZ  A ---- P 96:174:00000 96:176:86369 DORNE MARGOLIN B       128
 GRAZ  A ---- P 96:177:00000 96:182:86369 DORNE MARGOLIN T       457
-SITE/ANTENNA
+SITE/ECCENTRICITY
 GRAZ  A ---- P 96:174:00000 96:176:86369 UNE   2.0680   0.0000   0.0000
 GRAZ  A ---- P 96:177:00000 96:182:86369 UNE   1.9640   0.0000   0.0000
-SITE/ECCENTRICITY
+SOLUTION/EPOCHS
 GRAZ  A    1 P 96:174:00000 96:182:86369 96:178:00000
-SOLUTION/EPOCHS

Note that in this case no SOLN codes are required in the SITE/...
blocks! The records are well ordered by their data start/stop
fields. This is a change from the accepted Sinex v0.05 usage.
