Adding FCS online gain used on DEP in offline DB (star-bnl#668)
Browse files Browse the repository at this point in the history 
Adding FCS online gain used on DEP in offline DB which will be used for
offline trigger emulation (StFcsTriggerSimMaker). Offline DB already has
tables pushed. Here is code needed to reading of those tables, and using
them. Assorted macros to push those into DB and input files are also in
here for future reference/updates. Those gainOnline tables will be only
useful for trigger emulation in offline, and other analysis only uses
gain and gaincorr for offline energy gain calibrations.
