Detailed Description

2D representation of charge deposited in the TDC/wire plane

Hits are assumed to be made from deconvoluted, unipolar, calibrated signals. They identify a charge deposit in a specific location and time; the location is absolute and unique in the detector, while the time is relative to the start of sampling (tick time).

The version 14 of recob::Hit introduces the following changes:
