They are required for processing NIMS EDRs into cubes and tubes, and are available with the EDRs or with the ISIS software as follows. Kay Edwards' map of Galileo boom obscurations as a function of scan platform cone and clock angles is used to remove boom interference from NIMS products. It is available on the various NIMS EDR CD volumes, as well as with the ISIS system. Dark values must be subtracted from raw NIMS data numbers before conversion to radiance units. Dark files are average dark current files derived from "heaven dark" or other special observations at different times in the various encounters, or from off-limb data taken during some observations. They are available on the various NIMS EDR CD volumes, or may be generated from EDR data with ISIS software. NIMS instrument sensitivities and other instrument parameters are required for the conversion of raw NIMS data numbers to radiance units. They are available in NIMS Calibration files and are distributed with the ISIS system. Note that improved versions will be released as developed.
