Enumeration Type Documentation

enum larlight::FEM::DISCRIMINATOR

PMT discriminator type.

Enumerator:

BASE_DISC	lowest disc. threshold so-called disc. 0
COSMIC_DISC	discriminator for cosmics
MICHEL_DISC	discriminator for michel electrons (not used, just a place hlder)
BEAM_DISC	discriminator for signal within the beam window
BEAM_WIN	discriminator for beam window (forced N samples read-out)
DISC_MAX

enum larlight::FEM::FEM_WORD

Defines PMT word-type.

Enumerator:

UNDEFINED_WORD	Word type ... undefined.
EVENT_HEADER	A signal word (no data) to flag the start of headers.
FEM_HEADER	Event header word.
FEM_FIRST_WORD	First word in the event (after the event header, before channel data ).
CHANNEL_HEADER	Channel header word.
CHANNEL_WORD	Channel word such as ADC sample.
CHANNEL_LAST_WORD	Last word per channel-wise readout.
FEM_LAST_WORD	Last word per fem.
EVENT_LAST_WORD	Last word in the event.
