| Description: The gain_mode_id_ir element identifies the gain state of the IR channel. Gain is a constant value which is multiplied with an instrument's output signal to increase or decrease the level of that output. In PDS3, for VIMS the keyword GAIN_MODE_ID was multi-valued, with the specific meaning of each value based on the order of the given values. For VIMS in PDS4, this keyword has been replaced by two specific attributes. Following is a list of PDS3 keyword position indicies and the corresponding PDS4 attribute. PDS3 PDS4 [1] gain_mode_id_ir [2] gain_mode_id_vis |
