keyword=zero_VDC hits events in gammap99 dataI took a look at the VDC multiplicity in the gammap-99 run.
Run-2965 for example, with 6% radiator in, E0=4.793 GeV
beam on LH2 target. The h-arm was at 35.68 degree, momentum
set to 2.3446 GeV. No other particle ID cuts.
Noticed some zero_VDC hits events.
