Photon Reconstruction in b1pi events 04/25/2012

50,000 b1pi events. EM background on. svn rev 9031.

All plots use thrown vertex information to decouple photon analysis from tracking.

BCAL

mcsmear behavior is modified so that noise hits do not affect timing of non-dark hits. Normal time-smearing still-applied.

Thrown photons

Reconstructed photons

These come from DNeutralParticleHypothesis. At this stage the only cut that has been applied is rejecting clusters geometrically matched to charged tracks (this matching code is somewhat arcane and probably should be examined more closely. It does allow more than one cluster match per track).
