Back to [Winter2016 DVCS run plan]
θcalo [deg]= 25., θSTAND [deg]= ??.
Need to remove the plastic shield.
Calorimeter-Target distance =6.2m
Unrastered beam (which means beam current at less than 5 uA).
LHRS in positive polarity.
DAQ: DVCS config, trigger is S0+S2, autovalidation.
angleLHRS= 38.04 [deg]
momentum LHRS= 2.127 GeV
