Following spreadsheets provide temperature dependant velocity scales. Each file contains 13 columns (one column for every temperature window) with velocity values for 512 channels. Temperature windows are as following: <180 K, 180-190K, 190-200K, 200-210K, 210-220K, 220-230K, 230-240K, 240-250K, 250-260K, 260-270K, 270-280K, 270-290K,>280K (calibration is provided only for temp. windows where we have calibration data from Martian surface). These are standard scales for most measurements (unless stated otherwise in measurement's description):
