The H2SUSFMY M2 OSEMS were adjusted such that the flags were out of the LED beam path for an open light offset measurement could be taken. These measurements were performed earlier but with different results. The previous open-light cts were much lower than those measured today. The OSEMs were backed off the flags until the ADC cts levelled off.  Three of the OSEMs had open light counts above ~25000 cts with the "LR" OSEM only at ~22000 cts.  The OSEMs were then aligned such that the flags were occulting about half of the beam path.  The attached image is a snapshot of the new alignment.  The 'H2:SUS-FMY_M2_OSEMINF_*_OUT_DQ' now read around zero.

The same 'tdsavg' command was used to gather the average ADC cts over a 30-second time span. The signs of these values were flipped, and the values halved.  These are the new offsets in the 'H2:SUS-FMY_M2_OSEMINF_*_OFFSET' values.  The gains calculated by normalizing these results to 30000cts.

The new offsets are:
'H2:SUS-FMY_M2_OSEMINF_UL_OFFSET' = -12936 cts
'H2:SUS-FMY_M2_OSEMINF_LL_OFFSET' = -12827 cts
'H2:SUS-FMY_M2_OSEMINF_UR_OFFSET' = -12819 cts
'H2:SUS-FMY_M2_OSEMINF_LR_OFFSET' = -11181 cts

New gains:
'H2:SUS-FMY_M2_OSEMINF_UL_GAIN' = 1.16
'H2:SUS-FMY_M2_OSEMINF_LL_GAIN' = 1.169
'H2:SUS-FMY_M2_OSEMINF_UR_GAIN' = 1.17
'H2:SUS-FMY_M2_OSEMINF_LR_GAIN' = 1.342

Previous offsets:
'H2:SUS-FMY_M2_OSEMINF_UL_OFFSET' = -3697 cts
'H2:SUS-FMY_M2_OSEMINF_LL_OFFSET' = -12915 cts
'H2:SUS-FMY_M2_OSEMINF_UR_OFFSET' = -8545 cts
'H2:SUS-FMY_M2_OSEMINF_LR_OFFSET' = -11282 cts

Previous gains:
'H2:SUS-FMY_M2_OSEMINF_UL_GAIN' = 4.056
'H2:SUS-FMY_M2_OSEMINF_LL_GAIN' = 1.161
'H2:SUS-FMY_M2_OSEMINF_UR_GAIN' = 1.755
'H2:SUS-FMY_M2_OSEMINF_LR_GAIN' = 1.329
