Detailed Description

Concrete CSCIndexer class appropriate for CSC Conditions Data access for CMS startup (2008-2013) in which most ME4/2 chambers do not exist and the 48 ME1/1A strips are ganged into 16 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 at start-up of CMS in 2008. with rings ME11, ME12, ME13, ME21, ME22, ME31, ME32, ME41 totalling 234 chambers per endcap. But ME42 is appended (to permit simulation studies), 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

CSCIndexerBase::stripChannelIndex returns
1-217728 (CSCs 2008), 217729-252288 (ME42) (and ME1a channels are always channels 65-80 of 1-80 in ME11)

CSCIndexerBase::chipIndex returns
1-13608 (CSCs 2008), 13609-15768 (ME42)

CSCIndexerBase::gasGainIndex returns
1-45144 (CSCs 2008), 45145-55944 (ME42)

Warning
This uses magic numbers galore!!
EVERY LABEL COUNTS FROM ONE NOT ZERO.

Member Function Documentation

IndexType CSCIndexerStartup::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)

Warning
: the ME1a CFEB is just the last 1 of the 5 total in each layer of an ME11 chamber. So, the input of ir=4 is will just return the same 5 total chips per whole ME11.

Considers ME42 as standard 5 chip per layer chambers.

Implements CSCIndexerBase.

Definition at line 162 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::chipsPerOnlineLayer ( IndexType  is,
IndexType  ir 
) const
inlinevirtual

Number of Buckeye chips per layer in an online chamber in ring 'ir' of station 'is'. Works for ME1a (ring 4 of ME1) too.

'Online' ME11 for the startup is considered as a single chamber with 5 chips

Implements CSCIndexerBase.

Definition at line 98 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::chipStart ( IndexType  ie,
IndexType  is,
IndexType  ir 
) const
inlinevirtual

Linear index for 1st Buckeye chip in offline ring 'ir' of station 'is' in endcap 'ie'.

Endcap label range 1-2, Station label range 1-4, Ring label range 1-3.

Warning
: while ME1a chip is the last 1 of the 5 chips total in each layer of an ME11 chamber, here the ME1a input ir=4 defaults to the ME1b start index (ir=4 <=> ir=1).

Implements CSCIndexerBase.

Definition at line 176 of file CSCIndexerStartup.h.

int CSCIndexerStartup::dbIndex ( const CSCDetId &  id,
int &  channel 
) const
virtual

Build index used internally in online CSC conditions databases (the 'Igor Index')

This is the decimal integer ie*100000 + is*10000 + ir*1000 + ic*10 + il
(ie=1-2, is=1-4, ir=1-4, ic=1-36, il=1-6)
Channels 1-16 in ME1A (is=1, ir=4) are reset to channels 65-80 of ME11.

Implements CSCIndexerBase.

Definition at line 119 of file CSCIndexerStartup.cc.

std::pair< CSCDetId, CSCIndexerBase::IndexType > CSCIndexerStartup::detIdFromChipIndex ( IndexType  ichi) const
virtual

CSCDetId + chip within chamber from conditions data chip index.

Warning
This function changes meaning with ganged and unganged ME1/1a. If ME1/1a is ganged then an ME1/1a chip index returns ME1/1b CSCDetId + chip=5.
If ME1/1a is unganged then an ME1/1a chip index returns ME1/1a CSCDetId + chip# in range 1-3.

Implements CSCIndexerBase.

Definition at line 63 of file CSCIndexerStartup.cc.

CSCIndexerBase::GasGainIndexType CSCIndexerStartup::detIdFromGasGainIndex ( IndexType  igg) const
virtual

CSCDetId + HV segment + chip within chamber from conditions data gas gain index.

Warning
This function changes meaning with ganged and unganged ME1/1a. If ME1/1a is ganged then an ME1/1a gas gain index returns ME1/1b CSCDetId + HVsegment=1 + chip=5.
If ME1/1a is unganged then an ME1/1a gas gain index returns ME1/1a CSCDetId + HVsegment=1 + chip# in range 1-3.

Implements CSCIndexerBase.

Definition at line 137 of file CSCIndexerStartup.cc.

std::pair< CSCDetId, CSCIndexerBase::IndexType > CSCIndexerStartup::detIdFromStripChannelIndex ( LongIndexType  ichi) const

IndexType CSCIndexerStartup::onlineRingsInStation ( IndexType  is) const
inlinevirtual

How many online rings are there in station 'is'=1, 2, 3, 4 ?

Warning
: ME1a + ME1b are considered as single ME1/1 'online' rings for the startup

Implements CSCIndexerBase.

Definition at line 59 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::sectorStart ( IndexType  ie,
IndexType  is,
IndexType  ir 
) const
inlinevirtual

Linear index for 1st Gas gain sector in ring 'ir' of station 'is' in endcap 'ie'.

Endcap label range 1-2, Station label range 1-4, Ring label range 1-4 (4=ME1a)

Warning
: ME1a chip is the last 1 of the 5 chips total in each layer of an ME11 chamber, and an input ir=4 in this case would give the same result as ir=1

Implements CSCIndexerBase.

Definition at line 201 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::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 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 channels numbering is implemented.

Implements CSCIndexerBase.

Definition at line 120 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::stripChannelsPerOfflineLayer ( IndexType  is,
IndexType  ir 
) const
inlinevirtual

Number of strip readout channels per layer in an offline chamber with ring 'ir' and station 'is'. Works for ME1a (ring 4 of ME1) too.

Assume ME1a has 16 ganged readout channels.

Implements CSCIndexerBase.

Definition at line 72 of file CSCIndexerStartup.h.

IndexType CSCIndexerStartup::stripChannelsPerOnlineLayer ( IndexType  is,
IndexType  ir 
) const
inlinevirtual

Number of strip readout channels per layer in an online chamber with ring 'ir' and station 'is'. Works for ME1a (ring 4 of ME1) too.

Assume ME1a has 16 ganged readout channels. Online chamber has 64+16=80 channels.

Implements CSCIndexerBase.

Definition at line 85 of file CSCIndexerStartup.h.

LongIndexType CSCIndexerStartup::stripChannelStart ( IndexType  ie,
IndexType  is,
IndexType  ir 
) const
inlinevirtual

Linear index for 1st strip channel in ring 'ir' of station 'is' in endcap 'ie'.

Endcap label range 1-2, Station label range 1-4, Ring label range 1-4.

WARNING: while ME1a channels are the last 16 of the 80 total in each layer of an ME11 chamber, their start index here defaults to the start index of ME1a.

Implements CSCIndexerBase.
