Detailed Description

Concrete CSCIndexer class appropriate for CSC Conditions Data access after CMS long shutdown 1 (2013-2014) in which most ME4/2 rings are complete and the 48 strips in ME1/1A are unganged and so have 48 channels.
The conditions data are stored in an order based on the hadrware channel order so this class has to jump through hoops in order to map between that order and a CSCDetID order offline.

See documentation in base class CSCIndexerBase for more information.

Warning
This class is hard-wired for the CSC system expected after long shutdown 2013-2014 (LS1) of CMS.
The basic order is as for startup (pre-LS1) with rings ME11, ME12, ME13, ME21, ME22, ME31, ME32, ME41 totalling 234 chambers per endcap. Then ME42 is appended, so the chamber order is
+z ME11, ME12, ME13, ME21, ME22, ME31, ME32, ME41,
-z ME11, ME12, ME13, ME21, ME22, ME31, ME32, ME41,
+z ME42, -z ME42

It is further extended for unganged ME1a strip channels by appending +z ME1a, -z ME1a.

CSCIndexerBase::stripChannelIndex returns
1-217728 (CSCs 2008), 217729-252288 (ME42), 252289-273024 (unganged ME1a)

CSCIndexerBase::chipIndex returns
1-13608 (CSCs 2008), 13609-15768 (ME42), 15769-17064 (unganged ME1a).

CSCIndexerBase::gasGainIndex returns
1-45144 (CSCs 2008), 45145-55944 (ME42), 55945-57240 (unganged ME1a)

Warning
This has "magic numbers galore".
EVERY LABEL COUNTS FROM ONE NOT ZERO.

Member Function Documentation

IndexType CSCIndexerPostls1::chipsPerLayer ( IndexType  is,
IndexType  ir 
) const
inlinevirtual

Number of Buckeye chips indices per layer in a chamber in offline ring 'ir' of station 'is'.

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

Works for ME1a input as is=1, ir=4 Considers ME42 as standard 5 chip per layer chambers.

WARNING:

  • ME1a channels are considered to be unganged and have their own 3 chips (ME1b has 4 chips).
  • ME1b keeps 5 chips for the indexing purposes, however indices for the chip #5 are ignored in the unganged case.

Warning
: unganged ME1a has 3 own chips, which are currently appended to the end of the index range, ME1b still keeps 5 chips with the chip #5 index being unused.

IndexType CSCIndexerPostls1::stripChannelsPerLayer ( IndexType  is,
IndexType  ir 
) const
inlinevirtual

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. In the currently implemented upgrade scenario, the ME1b still keeps the 80 indices wide ranges inherited from Startup (with the last 65-80 indices remaining unused), while the ME1/1A unganged channels get their own 48 indices wide ranges.
