PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2004-02-01 NOTE = "Description of the CALIB directory contents for a MIMI CHEMS archive volume." END_OBJECT = TEXT END The calibration directory algorithm files (*_ALGO_*.TXT) and calibration data files (MIMI_CALIBRATION_vvvv.CSV). Algorithm files are named according to the convention: stttf_ALGO_vvvv.TXT where: s = sensor (l=LEMMS, c=CHEMS, i=INCA) ttt = data type (ACC/SCI=rates, FRT=fine rates, PHA=pulse height analysis, IMG=images) f = index representing format version of file (0-9 then A=Z) vvvv = data version of file Algorithm files contain brief descriptions of how to obtain useful, physical quantities from the data products. Each algorithm file applies to the data product files whose naming convention matches that of the algorithm file (e.g. CACCf_ALGO_vvvv.TXT applies to the MIMI_CHEMS_ACC files). Calibration data files are formatted as CSV files and contain the quantities required to execute the algorithms in the algorithms files. The INCA_IMAGES subdirectory contains INCA flux (exposure) factor matricies which may be used to convert the raw image data into fluxes. Included with each text file (*.TXT) are attached PDS labels. The CSV files are accompanied by detached PDS labels.

The next following published version of this file is version 0003. Versions 0001 and 0002 were intermediate products maintained within the MIMI team but not ready for publication.
