The CALIB directory contains the calibration files used in the processing
of the raw data or needed to use the data products on the volume.
If a folder contains no data it will not be generated.

IFMS data:
The used calibration routines are described in two documents:
VEX-VRA-IGM-DS-3011.PDF and VEX-VRA-IGM-DS.3012.PDF, for the Doppler and 
Ranging processing software, respectively. The documents can be found in the
folder /DOCUMENT/VRA_DOC/.

IFMS data:
The .RAW files contain the header information and the data in Level 1a. This
is separated for Level 1b files, where the header is in the .CFG file and the
data is in the .TAB file. There is only one label file for the .CFG and .TAB
files in level 1b. More detailed information can be found there as well.
                                                                              
     Each object is in ASCII; the files have a fixed length of
characters per line, but this fixed length can differ from file to file. 
The details and correct values can be found in the label header of each file. 
Eachline is delimited with a carriage-return (ASCII 13) line-feed 
(ASCII 10) pair.
