Gain Correction Factors

...

Definition

• The gain correction factor is defined for images averaged over 100 events for good pixels as
  g(i,j) = <Amplitude in ASIC> / Amplitude(i,j),
  where i and j are the pixel indexes in ASIC.
• The gain correction factor is set to "0" for bad pixels.

The gain correction factors for runs 901, 902, and low gain 903, 904, 905, and 906

with transmission 0.002, 0.005, 0.005, 0.1, 0.5, 1, respectively
