Detailed Description

Identifier class for hierarchy of Endcap Muon detector components.

Ported from MuEndDetectorId but now derived from DetId and updated accordingly.

Allows access to hardware integer labels of the subcomponents of the Muon Endcap CSC detector system.

The STATIC member functions can be used to translate back and forth between a layer/chamber 'rawId' and the set of subdetector labels.

Warning: EVERY LABEL COUNTS FROM ONE NOT ZERO.

Methods for reordering CSCDetId for ME1 detectors.

Internally the chambers are ordered (Station/Ring) as: ME1/a (1/1), ME1/b (1/2), ME1/2 (1/3), ME1/3 (1/4) i.e. they are labelled within the DetId as if ME1a, ME1b, ME12, ME13 are rings 1, 2, 3, 4. The offline software always considers rings 1, 2, 3, 4 as ME1b, ME12, ME13, ME1a so that at least ME12 and ME13 have ring numbers which match in hardware and software!

Returns the unique integer 'rawId' which labels each CSC layer.

The arguments are the integer labels for, respectively,
endcap, station, ring, chamber, layer.

Warning: The input int args are expected to be .ge. 1 and there is no sanity-checking for their upper limits.; The returned integers are not necessarily consecutive, i.e. there are gaps. This is to permit computational efficiency starting from the component ids.

int CSCDetId::triggerCscId ( ) const

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 CSCDetId::triggerSector ( ) const

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.
