Detailed Description

This class reconstructs RecHits from Digis for CASTOR 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.
