All SEI GS13s are now set in High Analog Gain without Whitening except HAM6 and BS (Stage2.) This standard High Gain configuration is with both FM4 & 5 Off in the GS13 INF module, H1:ISI-HAM5_GS13INF_H1 for example.
For HAM6, because of the shutter hit to the ISI, the GS13s are run with Low Analog Gain without Whitening. This configuration is with FM4 On and FM5 Off.
For BS, because of the hit to the ISI when the MICH acquires, we run the GS13s in the standard low Gain configuration of Analog Low Gain and Whitening. This has both FM4 & 5 On.
These configurations are set in SDF.
