[d2n-analysis-talk] PR Gain-Matching & Database Changes

[David Flay]

Hi all,

Dr. Meziani has suggested that I double check my calibration coefficients
in the PR.  It turns out that the coefficients are off for all of the
momenta that are not p = 1.20 (I calibrated off of this momentum).  So, I
am in the process of recalculating coefficients for each momentum
separately, so that the pion peaks align to 100 channels in the ADC.

This of course implies that there will now be 14 different sets of
gain-matching coefficients.  As I calculate these, I am doing an overhaul
of the 'StartType.pl' Perl script which will account for all these
different calibration constants (also, each time-stamped directory will
now have these new coefficients).  I am hoping to have this process
finished by the middle of the coming week, but I will let you know when
the DB and StartType.pl script are ready.
