Detailed Description

Definitions shared by the classes of the MM trigger processor emulation.

The electronics constants describe the nominal readout of one MM sector layer (all eight planes are read out the same way). They are not part of the readout geometry, which only knows the active strips of each module (firstStrip, numStrips): a few nominal strips at the module edges are not mounted, but the electronics numbering still counts them.
