The same procedure for the H2 ITMY L1 Open Light voltages were recorded for the H2 ITMY L2 Open Light voltages. A 30-second average of the H2:SUS-ITMY_L2_OSEMINF_*_IN1_DQ channels with thetdsavg
command-line tool was used to record their values. Their values were halved, multiplied by (-1), and entered into the H2:SUS-ITMY_L2_OSEMINF_*_OFFSET channels. The gains for these channels were calculated by normalizing the open light counts to 30,000cts.Open Light (cts) UL = 27204.7 LL = 17354.3 UR = 19496.5 LR = 20515.5 Offsets [-(open light)/2] (cts) UL = -13602 LL = -8677 UR = -9748 LR = -10258 Gains [30000 / (open light)] UL = 1.103 LL = 1.729 UR = 1.539 LR = 1.462 Open Light counts after normalization [tdsavg] (should be ~15000) UL = 14998.4 LL = 14997 UR = 14999.8 LR = 14993.3
