Detailed Description

ABC for CSCIndexer classes.

A CSCIndexer class provides a linear index for various sublevels of the endcap muon CSC system for use in access to information stored in the Conditions Database. Only concrete derived classes can be instantiated.

It supplies a linear index for:

Each chamber of the CSC system: range 1-468 (CSC system as installed 2008) 469-540 for ME42
Each layer of the CSC system: range 1-2808 (CSCs 2008) 2809-3240 for ME42
Each strip channel of the CSC system: range 1-217728 (CSCs 2008) 217729-252288 for ME42
Each Buckeye chip (1 for each layer in each CFEB) of the CSC system: range 1-13608 (CSCs 2008) 13609-15768 for ME42
Each Gas Gain Sector (1 for each [CFEB*HV segment] combination in each layer): range 1-45144 (CSCs 2008) 45145-55944 for ME42

The chamber and layer may be specified by CSCDetId or labels for endcap, station, ring, chamber, layer.

The strip channel is a value 1-80 for most chambers.
ME1/3 and ME1/1B have 64 channels.
ME1/1A has 16 channels at CMS startup (2008-2013) and 48 channels after Long Shutdown 1 ('LS1' 2013-2014)
The chip number is a value 1-30 (or 24: ME13 chambers have only 24 chips.)

The main user interface is the set of functions
chamberIndex(.)
layerIndex(.)
stripChannelIndex(.)
chipIndex(.)
But the other functions are public since they may be useful in contexts other than for Conditions Data for which the above functions are intended.

The terminology "label" can be confusing.
The CSC project typically refers to an element of the CSC detector by hardware labels endcap (+z, -z), station (1-4), ring (1-3), chamber (1-18 or 1-36 depending on ring), layer (1-6). Strips (and wiregroups) are number 1-N where N is the total number of strips in a given layer.
Offline, we turn +z, -z into integers 1, 2 and extend the ring index to 4 to mean ME1/1A (leaving ring 1 in station 1 to mean ME1/1B when dealing with strip planes. Since there is only one common wire plane sometimes ring 1, station 1 means the entire ME1/1 and sometimes just ME1/1B.) So in offline code, when we talk about "labels" for an element, we typically mean these integer values.
For example, strip 71 of layer 4 of chamber 17 of ME-3/1 is labelled {ie=2, is=3, ir=1, ic=17, il=4, istrip=71}. However, in CSCIndexer classes, "label" may be generalized to mean more than this. For example, the "chamberLabel_" vector encodes these integer labels for a chamber, and does not just mean the value ic=1-18 or 36.

Warning: EVERY LABEL COUNTS FROM ONE NOT ZERO.; Contains a number of non-virtual method that derived classes are not expected to override! TODO: add 'final' attribute to those non-virtual methods after full migration to gcc4.7

Linear index for Gas gain sector, based on CSCDetId 'id', the HV segment# and the chip#. Note: to allow method overloading, the parameters order is reversed comparing to the (id,strip,wire) method

Output is 1-45144 (CSCs 2008) and 45145-55944 (ME42) and 55945-57240 (ME1a)

Warning: : Use at your own risk! You must input labels within hardware ranges. No trapping on out-of-range values! The supplied CSCDetId must be a layer id, and ichip must be h/w chip number in a chamber. E.g., if you provide ME1a id in ganged case, it would still be treated the same as whole ME11 id, but ichip must be 5 for it to make sense!

◆ stripChannelsPerLayer()

virtual IndexType CSCIndexerBase::stripChannelsPerLayer	(	IndexType	is,

pure virtual

Number of strip channel indices for a layer in a chamber defined by station number 'is' and ring number 'ir'.

Station label range 1-4, Ring label range 1-4 (4=ME1a)

This depends on the ordering of the channels in the database. E.g., in startup scenario there are 80 indices allocated per ME1/1 layer with 1-64 belonging to ME1b and 65-80 belonging to ME1a. So the ME1/a database indices are mapped to extend the ME1/b index ranges, which is how the raw hardware chnnels numbering is implemented.

In the currently implemented upgrade scenario on the other hand, the ME1b still keeps the 80 indices wide ranges (with the last 16 of them remaining unused), while the ME1/1A gets its own 48 indices wide ranges.
