Detailed Description

Implementation of the local Level-1 Cathode Strip Chamber trigger. Simulates functionalities of the anode and cathode Local Charged Tracks (LCT) processors, of the Trigger Mother Board (TMB), and of the Muon Port Card (MPC).

Input to the simulation are collections of the CSC wire and comparator digis.

Produces four collections of the Level-1 CSC Trigger Primitives (track stubs, or LCTs): anode LCTs (ALCTs), cathode LCTs (CLCTs), correlated LCTs at TMB, and correlated LCTs at MPC.
