[BLAST_ANAWARE] back to the offsets

Hello all-

        Well my finals are done! I apologize, however, that I can not come
to Bates today as I will be on shift the next three days and today is
my only day to take care of a few weekday things.

Anyway, for the analysis meeting, I have
continued refining this new offset analysis of which Genya and I were
collaborating on last week. Attached are two new files, this time cutting
on 0.1 and 0.15 avg bin height. Genya, are these values even closer to
yours compared to the 0.25 cut?

-My plan is to test these offsets later today looking at the self timing
peak.

-Also, I set up the macro so that it calls a WriteCalib() in TBLScRecon
and creates a new calib file like always. Currently, I put a TString
containing run numbers in manually, does this exist in init.C (OK I still
haven't checked, Chris)

-I have just begun writing a short macro to determine offsets using the
flasher. This should be very easy to write since we don't have to worry
about finding histogram edges and can just grab the mean. This also
should avoid the "multi-run TChain delay" as we only need one run with 10K
events and all detectors will get 10K events with the flasher. Once this
is done I will compare it with the results of the macro based on Genya's
method. ***As JRC has said though I must ensure that the flasher has been
attenuated before I can trust the results****

See you tomorrow!

                                Pete
