[Clas12_calcom] 10:00 analysis meeting today

[Rafayel Paremuzyan]

Dear Fx,

Are you using the RUN_config::trigger? for decoding the trigger? in 
reality as Ben mentioned this before,
it captures very small portion of time window (few tens of ns) wrt 
readout window size (400 ns), while
the vtp2 reports triggers with 4ns time resolution in a 400 ns time 
interval,

However, if this skim is intended for trigger studies, I think will good 
to not ask anything about the trigger bit in the skim,
probably just Id==11 will be good. I have skimmed the converted root 
files with only id=11 requirement, and in total for 2219 and 2220 I
ended up with 70K events.
