[Halld-cal] Fwd: gamma confidence level plots

[Sean Dobbs]

Hi all,

I wanted to pass along these plots generated by Brad Cannon when he was
looking at gamma p -> p + gamma gamma K+ K- events in the 2017 data.

The plots are of the PID confidence levels for the photons both with no
timing cut at all, and with a loose timing cut of several ns.  I believe
that this CL is just based on the timing, so the results suggest that the
timing errors used  for the FCAL are in the right ballpark, but the BCAL
errors need to be updated.

Cheers,
Sean
