  • constants for ueddaq02 r401 are loaded correctly from the latest dark run r398
  • default gain factor for FL is 0.164 ADU/keV (or ~6keV~6 keV/ADU)
  • numeration of panels is defined in geometry looks correct
  • per-pixel gain range index is defined correctly =2 for FL.
  • pedestal subtraction works as expected: raw-peds has mean=0.6 ADU, raw RMS shrinks from 170 ADU to ~3 ADU raw-peds.
  • there may be a minor common mode offset ~0.6ADU, but common mode is not corrected for FL. Even if it is corrected, this would not resolve this issue.
  • default gain factor is defined correctly for FL is 0.164 ADU/keV
  • rms defined in dark r398 shows that panel/banks have significant spread/noise variation of factor 2-3 between panels.
  • plots of calib for "hot" and "cold" ASICs show that RMS is significantly different. 
  • in this case application of the common threshold is a bad idea
