[Clas12_calcom] Engineering Run Part #2

[Francois-Xavier Girod]

Dear all

I would like to reiterate a call to individuals who intend to perform
detector calibration, for a definition of skim information in the following
form :

- a list of all the banks you need, ideally something like this :
"RUN::rf","RUN::config", "TimeBasedTrkg::TBTracks", "ECAL::clusters", ...
- a condition on selecting events, ideally a list of consecutive cuts to
apply to variables from specified bank variables. In principle this is
quite arbitrary, and we can define as elaborated conditions for your
skimming strategy as necessary

I will produce the skim files for you, using our golden runs, which will
facilitate and unify the calibration process

Looking forward to your input

Best regards
FX
