Pedestal = detector background

  1. We should ALWAYS have the stopper IN for taking pedestals because everything else will be penetrated more or less by the high photon energy FEL 
  2. > takepeds
  3. > makepeds -u unixID -r runNumber -F (-q queueID) 
    • -q can be omitted if not sure

Note: every time we retake and remake the pedestal, we need to shut down and reconfigure the DAQ to pick up the changes
