◆ analyze()

void OMTFPatternMaker::analyze	(	const edm::Event &	iEvent,

Get the simulated muon parameters

Filter digis by dropping digis from selected (by cfg.py) subsystems

Loop over all processors, each covering 60 deg in phi

Input data with phi ranges shifted for each processor, so it fits 11 bits range

Connections maps are made by hand. makeConnetionsMap method provides tables for checking their consistency.

Implements edm::one::EDAnalyzerBase.
