5. epics.cal
a new ascii file epics.cal is checked into Blast_Params. It includes
run depended information in order to correctly parse the epics,
scaler events. for instance it contains a "spinflip" entry that
indicates if spin flipper is on for each run.
This file is meant to synch the library with the run specific
operations in charge.C without recompilation.
read the file which has detailed comments for more information.
6. new entries to the lr ntuple:
nev: event number, it is trivial in lr but it makes it possible to
refer to the exact event in coda file from flr, flrpm ntuple.
nrun: though with the data set feature in init.C, knowing the run
number for each event hardly has any advantage, we nevertheless
added it
tep: time of the epics event linked to this physics event round up to
second
tsc: time of the scaler event linked to this physics event
an epics/scaler event is said to be linked to a physics event, if
this epics/scaler event bears a time coda time stamp earlier than the
physics event, and the next epics/scaler event bears a coda time stamp
later than the physics event. "time-tep", or "time-tsc" should not be
very large. in fact, the difference is 0 or 2 seconds most of the
time. a large difference means the epics and scaler info associate to
that particular physics event may not be accurate.
LADS raw signals are in lr now:
"t15l:a15l:p15l:n15l:t15r:a15r:p15r:n15r:"
"t20l:a20l:p20l:n20l:t20r:a20r:p20r:n20r:"
see lrn.h at the top for the entry definitions in lr ntuple.
