Detailed Description

Define the p0d specific constants used to decode a geometry identifier. The P0D field is 25 bits divided into a sequence identifier, and a field value.

sssss ffffffffffffffffffff
s(4)  -- The sequence identifier (0 to 15)
f(21) -- The field value associated with a sequence id.

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

Enumeration Type Documentation

P0DSeqId

enum ND::GeomId::Def::P0D::P0DSeqId

Define the sequences required in the P0D.

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

Variable Documentation

kSeqIdMSB

const GeomIdBit ND::GeomId::Def::P0D::kSeqIdMSB = Def::kSubDetectorMSB

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