Detailed Description

Define the ECal specific constants used to decode a geometry identifier. The ECal field is 25 bits divided into a sequence identifier, and a field value.

ssss mmm fffffffffffffffffff
s(4)  -- The sequence identifier (0 to 15)
m(3)  -- The ecal module number
f(18) -- The field value associated with a sequence id.

Depending on the particular sequence, the field values may be further sub-divided.

§ ECalSeqId

enum ND::GeomId::Def::ECal::ECalSeqId

Define the sequences required in the ECal.

Enumerator
kGlobal	A global volume. This is used for identifiers that refer to volumes which contain other geometry identifiers.
kScintillator	A scintillator bar.

§ kModuleMask

const GeomIdMask ND::GeomId::Def::ECal::kModuleMask

Initial value:

= MAKE_MASK(kModuleMSB,

kModuleLSB)

Definition at line 475 of file ND280GeomIdDef.hxx.

§ kModuleMSB

const GeomIdBit ND::GeomId::Def::ECal::kModuleMSB = kSeqIdLSB-1

The module id field. This is always zero for the down stream ecal. For the P0D and Tracker ECals, the is 0) -x bottom 1) +x bottom 2) -x side 3) +x side 4) -x top 5) +x top

Definition at line 473 of file ND280GeomIdDef.hxx.

§ kSeqIdMSB

const GeomIdBit ND::GeomId::Def::ECal::kSeqIdMSB = Def::kSubDetectorMSB

The most significant bit of the sequence identifier field. The sequence id field can have values between 0-15.
