DISCUSSION

The results are requested as Sinex files (see format), with a normalized 
description of the analyses. Special attention should be paid to the 
recommended constraints. The time interval of the series of Sinex files is 
one week. To match the product structure already existing in parallel services, 
the start of each week is Sunday, 00:00 UT. The series of Sinex files should start 
with data on 29 Sept 2002, 00:00 UT.

Reminder of the filename structure for Sinex files

      cccYYDDDtuVV.snx.Z           
Where
      ccc = center three-character acronym
      YY  = last two digits of year of the first observation 
      DDD = three-digit day of year of the first observation.
      t   = type of the solution : m/w/d for monthly/weekly/daily solutions
      u   = d for "Doris only", c for "multitechnique"
      VV  = version number of the solution. Please use the following 
      01: EGM96   02: GRIM5-C1   03: GGM01C   13: GGM01S   04: EIGEN-GRACE01S
      snx = fixed part (refers to the format)
      Z (upper cap) points to compacted file (Unix)

Examples: gau solutions based on two gravity field models, EGM96 and
          GGM01, using data starting 29 Sept 2002 (Sunday, 00:00 UT)

          gau02272wd01.snx.Z   gau02272wd03.snx.Z   
          gau02279wd01.snx.Z   gau02279wd03.snx.Z   
          ...                  ...

Requested documentation file 

One IDS standard analysis description file may be used for the set of solutions 
referred to the various gravity fields. Use the filename: cccwd00.snx.dsc 

Providing product and documentation files to the IDS Data Centers

The files will be stored in a special area (products/2003campaign) at the IDS 
Data Centers. Analysis centers should contact C. Noll or E. Gaulué to organise 
their submissions.

For more details on the IDS file naming and data center structure, see here.
