[clas12_rgk] Evgeny's puzzle

[Francois-Xavier Girod]

Dear all

I took a look at Evgeny's events and uploaded some information on the docDB
https://clas12-docdb.jlab.org/cgi-bin/DocDB/private/ShowDocument?docid=502

I was not able to produce CED pictures because the input DSTs from the
trains do not have detector banks
However I think we can still see three kinds of events
(1) CVT "ghost" tracks around polar angle = 90 degrees (5% of events)
(2) CVT duplicate tracks correlated with the proton (22.5% of events)
(3) accidental tracks (72.5% of events)

Some samples of 1k events from each category are available under
/work/clas12/fxgirod/Evgeny/
In principle we can filter these events from decoded files, reconstruct
them specifically and look at them on CED

Please let me know if you have questions of suggestions

Best regards
FX
