#include <CSCIndexerPostls1.h>
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.
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)
