Detailed Description

This class reconstructs RecHits from Digis for ZDC by addition of selected time samples, pedestal subtraction, and gain application. The time of the hit is reconstructed using a weighted peak bin calculation supplemented by precise time lookup table. A consumer of this class also has the option of correcting the reconstructed time for energy-dependent time slew associated with the QIE.

A sencon method based on a based on a event by event substraction is also implelented. signal = (S4 + S5 - 2*(S1+S2+S3 + S7+S8+S9+S10))*(ft-Gev constant) where SN is the signal in the nth time slice
