Detailed Description

This class simulates the functionality of the cathode LCT card. It is run by the MotherBoard and returns up to two CathodeLCTs. It can be run either in a test mode, where it is passed arrays of halfstrip and distrip times, or in normal mode where it determines the time and comparator information from the comparator digis.

The CathodeLCTs come in distrip and halfstrip flavors; they are sorted (from best to worst) as follows: 6/6H, 5/6H, 6/6D, 4/6H, 5/6D, 4/6D.

Date

May 2001 Removed the card boundaries. Changed the Pretrigger to emulate the hardware electronic logic. Also changed the keylayer to be the 4th layer in a chamber instead of the 3rd layer from the interaction region. The code is a more realistic simulation of hardware LCT logic now. -Jason Mumford.
