EXTRAS Directory Contents
The EXTRAS directory contains subdirectories of IDFS_DATA and SPICE_DATA
that are used as input files for generating the MEX ASPERA-3 data releases.
The IDFS_DATA_* subdirectories and contents are in zip files and have
corresponding label files. A new IDFS_DATA_* zip file and corresponding
label are added for each data release. The new IDFS_DATA_* zip file
contains the IDFS data that are used to generate this data release.
The files listed below are found in this directory.
EXTRINFO.TXT - The file you are reading.
IDFS_DATA_❮time period❯.ZIP - Zip files of the IDFS_DATA_❮time period❯
directories containing subdirectories of
the IDFS database and data files used as
input to generate the PDS files, where
time period = 'NEV', 'IC', or MMMYYYY
MMM is 3-character month, and
YYYY is 4-digit year.
It is important to note that the 'NEV'
and 'IC' time periods do NOT correspond
to the Mission defined time periods.
For ASPERA-3, the 'NEV' time period is
when data are sampled closer to Earth,
so EARTH is used as the reference target.
The 'IC' time period is when data are
taken closer to Mars during cruise but
before the first Mars orbit.
IDFS_DATA_❮time period❯.LBL - PDS label describing the contents of the
IDFS_DATA_❮time period❯.ZIP file.
MEX_SCIENCE_SUBPHASE_DEFS.TAB - The Mars Express Mission Subphases Index
Table used in determining the values for
the MISSION_PHASE_NAME keywords in the
PDS detached data labels.
MEX_SCIENCE_SUBPHASE_DEFS.LBL - PDS label describing the contents of the
MEX_SCIENCE_SUBPHASE_DEFS.TAB file.
SPICE_DATA - Directory containing the CK, FK, IK, LSK, ORBNUM, PCK,
SCLK, and SPK subdirectories of SPICE kernels used in
describing the geometry and position information of the
data files in the archive volume.
