Detailed Description

Produces GEM pad clusters from at most 8 adjacent GEM pads. Clusters are used downstream in the CSC local trigger to build GEM-CSC triggers and in the muon trigger to build EMTF tracks

Based on documentation provided by the GEM firmware architects

Author: Sven Dildick (TAMU), updated by Giovanni Mocellin (UCDavis)

** Notes on chambers and cluster packing algorithm **

Based on: https://gitlab.cern.ch/emu/0xbefe/-/tree/devel/gem/hdl/cluster_finding/README.org (Andrew Peck, 2020/06/26)

GE1/1 chamber has 8 iEta partitions and 1 OH GE2/1 chamber has 16 iEta partitions and 4 OH (one per module)

Both GE1/1 and GE2/1 have 384 strips = 192 pads per iEta partition

GE1/1 OH has 4 clustering partitions, each covering 2 iEta partitions GE2/1 OH has 4 clustering partitions, each covering 1 iEta partition

Each clustering partition finds up to 4 clusters per BX, which are then sent to the sorter. The sorting of the clusters favors lower eta partitions and lower pad numbers.

The first 8 clusters are selected and sent out through optical fibers.
