attribute definition: mro:calibration_lamp_level
The CALIBRATION_LAMP_LEVEL keyword provides the level of the CRISM calibration lamp identified by LIGHT_SOURCE_NAME. 0 indicates that a lamp is unpowered. Also if the lamp level is a non-zero value, MRO:CALIBRATION_LAMP_STATUS must equal ON, OPEN LOOP or CLOSED LOOP. For any lamp, if MRO:CALIBRATION_LAMP_STATUS = ON or OPEN LOOP, the lamp level is proportional to the current being supplied to the lamp. In the special cases of LIGHT_SOURCE_NAME = SPHERE LAMP 1 or LIGHT_SOURCE_NAME = SPHERE LAMP 2, if MRO:CALIBRATION_LAMP_STATUS = CLOSED LOOP, then the lamp level gives the setting of the photodiode in the integrating sphere that provides feedback to control the lamp current.
