keyword=noticed zero hits events on VDCI took a look at the right arm trigger-1 events in run 1516.
The attached plots are the number of VDC hits on each plane.
The events are required to have a good gas cherenkov signal and
a good aeroal signal. The cuts are:
abs(rgassum)<2000.0&&abs(rgassum)>50.0&&
abs(raerosum)<50000.0&&abs(raerosum)>4000.0
Still, there're a lot of events which do not have VDC
hits.
Noticed that the lead_glass energy in a cluster
might be calculated in a way that a good tracking quality
was assumed. Do we have a raw lead glass sum on each
layer ?
