PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2016-11-04 NOTE = "Description of contents of CALIB directory" END_OBJECT = TEXT END The CALIB directory contains the calibration files used in the processing of the raw data or needed to use the data products of the volume. It should be noted that some calibration files listed in the CALIB tree diagram below may not be present in this data set. IFMS data: The used calibration routines are described in two documents: ROS-RSI-IGM-DS-3118.PDF and ROS-RSI-IGM-DS.3119.PDF, for the Doppler and Ranging processing software, respectively. The documents can be found in the folder /DOCUMENT/RSI_DOC/. 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. Each line is delimited with a carriage-return (ASCII 13) line-feed (ASCII 10) pair.
