C*IDS recommended initial values of mass and center of gravity coordinates in satellite reference frame
C*------------------------------
C*-reference document for information and history of changes: ftp://ftp.ids-doris.org/pub/ids/satellites/DORISSatelliteModels.pdf
C*-content:
C*  satellite 3-letter code
C*  satellite mass (kg)
C*  Xo (m)
C*  Yo (m)
C*  Zo (m)
C*  date of update (yyyy/mm/dd)
C*  source (ini = initial value from manufacturer given before launch; ssa = value provided by CNES/POD (SSALTO) after launch; and potentially some others)
C*  comments :
C*(1)Manufacturer's values replaced by CNES/POD values in ja1mass.txt too; See reference document for previous values
c*(2)These values are applied for the correction "center of mass - center of phase" in SARAL doris 2.2 data files from srldata087.001 (06-Nov-2014 12-Nov-2014); See reference document for previous values
c*(3)For HY-2C altimetry precise orbits the DORIS reference point location has been updated by adding +2 mm in the X, -10 mm in the Y, and +18 mm in the Z directions; note that the reference document gives only the updates adopted at CNES 
c*(4)For Sentinel-6A altimetry precise orbits the DORIS reference point location has been updated by adding +10 mm in the Y and +32 mm in the Z directions; note that the reference document gives only the updates adopted at CNES
c*(5)Computed by CNES from manufacturer’s values for the platform, and contribution of the solar arrays
