Ran over full minbias sample, found a few hundred events with the zero tower pt problem, some more with an isolation cut problem maybe?
Add config to test event with isolation issue.
Added crystal info tree to heatmap code
Removed crystal clusters where seed crystal tower had zero energy in fakes.
(i.e. all tower-based algs would not have that event)
Added tower energy check to efficiency code as well.
Updated plotting script to draw rate/eff with and without zero-towers.
Tighter gen:offline reco matching cut.
Print out flags of the EcalRecHit seed crystal in cluster.
Moved EcalRecHit flag check to function, store flag histograms for both rate & efficiency.
Lots of plotting updates.
