Detailed Description

This class reconstructs RecHits from Digis for HBHE, HF, and HO 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.
