HESSI GAIN PARAMETERS VERSION ["gain_generation"] RECORD: Version 1 (based on ground calibration data): 5/29/01 Version 2 (based on flight data): 4/2/02 Version 3 (flight data, including time dependence through 5/17/02): 7/1/02 As of 7/2/02, the *most recent* version of the gain parameters will be listed as version/generation 1000 (e.g. using file hessi_gain_vs_time.1000), so on this date hessi_gain_vs_time.1000 = hessi_gain_vs_time.3 As of 7/15/02, hessi_gain_vs_time.1000 = hessi_gain_vs_time.4 (fits to gain_vs_time now include data through early July instead of mid May)
