Member Enumeration Documentation

DriftState

enum TrkDriftCircleMath::DriftCircle::DriftState

state of the drift circle

Enumerator
EarlyHit
InTime	drift time too small to be compatible with drift spectrum
LateHit	drift time compatible with drift spectrum
EmptyTube	drift time too large to be compatible with drift spectrum
NotCrossed	channel without drift measurement

Definition at line 25 of file DriftCircle.h.
