Detailed Description

Class to calculate the deposited charge in one digi <-> time over threshold and vice versa

Author: D.-L.Pohl d.poh.nosp@m.l@fz.nosp@m.-juel.nosp@m.ich..nosp@m.de

This class calculates the time over threshold by using the charge of a pixel/strip. To calculate the TOT a simple capacitor model (integrator) is used. The charge time tr [ns] is assumed to be constant. This leads to a rising straight line. A constant current unloads the capacitor with a ratio of: a [e/ns]. The distance between the points of intersection between the resulting triangle and the threshold line is the TOT.
