int CSCTriggerNumbering::triggerCscIdFromLabels ( int  station,

Return trigger-level CSC id within a sector for an Endcap Muon chamber.

This id is an index within a sector such that the 3 inner ring chambers (20 degrees each) are 1, 2, 3 (increasing counterclockwise) and the 6 outer ring chambers (10 degrees each) are 4, 5, 6, 7, 8, 9 (again increasing counter-clockwise.)

This method knows which chambers are part of which sector and returns the chamber label/index/identifier accordingly. Beware that this information is liable to change according to hardware and software changes.

int CSCTriggerNumbering::triggerSectorFromLabels ( int  station,
int  ring,
int  chamber 
) [static]

The following functions transform standard chamber labels into their corresponding trigger labels.

Return trigger-level sector id for an Endcap Muon chamber.

This method encapsulates the information about which chambers are in which sectors, and may need updating according to hardware changes, or software chamber indexing.

Station 1 has 3 rings of 10-degree chambers.
Stations 2, 3, 4 have an inner ring of 20-degree chambers and an outer ring of 10-degree chambers.

Sectors are 60 degree slices of a station, covering both rings.
For Station 1, there are subsectors of 30 degrees: 9 10-degree chambers (3 each from ME1/1, ME1/2, ME1/3.)

The first sector starts at phi = 15 degrees so it matches Barrel Muon sectors. We count from one not zero.

Each station one sector has two 30 degree subsectors. Again, we count from one, not zero. Zero is an allowed return value though.

A return value of zero means this station does not have subsectors.
