Detailed Description

Correlates anode and cathode LCTs from the same chamber.

When the Trigger MotherBoard (TMB) is instantiated it instantiates an ALCT and CLCT board. The MotherBoard takes up to two LCTs from each anode and cathode LCT card and combines them into a single Correlated LCT. The output is up to two Correlated LCTs.

It can be run in either a test mode, where the arguments are a collection of wire times and arrays of halfstrip and distrip times, or for general use, with wire digi and comparator digi collections as arguments. In the latter mode, the wire & strip info is passed on the LCTProcessors, where it is decoded and converted into a convenient form. After running the anode and cathode LCTProcessors, TMB correlates the anode and cathode LCTs. At present, it simply matches the best CLCT with the best ALCT; perhaps a better algorithm will be determined in the future. The MotherBoard then determines a few more numbers (such as quality and pattern) from the ALCT and CLCT information, and constructs two correlated LCT "digis".
