Re: [BLAST_ANAWARE] offsets with 4000 series runs

Yes, ttl-ttr overlayed with ttr-ttl is supposed to be symmetric, that was
the goal. At first I used a lot of recon cuts like charge, vertex, etc.
but then, to gain statistics just used atl > 7500 && atr < 2500:atr > 7500
&& atl < 2500 and this worked nicely.

        Anyway, when I first ran the macro and the canvas popped up I just
saved it from the File menu as canvas.C. However, Chris has
since sent me the following:

hi pete,
  i would suggest saving it as ".root". it's a little more compact, and
you can view it from the blast account with "rv ttl-ttr_4103-4105.root"
--chris

Anyway, sure use it for PID, I assume the aim is to replace the existing
file so that we can do all crunching with this one.
