1. pi0 is taken as HT clusters  with no charge track in the  tower  with   max energy.

Charge separated Ws from Run 9, algo ver 4.1

Upper plot (fig 1) shows Ws reconstructed from ~100% of Run9 data with algo ver 4.1 , now using away ET veto.

First look at TPC slewing

 Calibrating padrow-by-padrow T0s showed evidence of dependence of T0s on anode HV: the padrows under anode section 7-6 (padrows 22-29) showed a shift of 15-20 ns for a reduction in voltage fr

Distortion effects on padrow shape

 Applying the following distortions:

vernier scan fit implementation

My code as written is producing unrealistically small cross sections, so I wanted to explicitly write out the way I'm performing the fit:
