Detailed Description

The reaction search: strip-sum scatters, beam gating and tagging.

Builds, per reaction strip, a two-dimensional scatter in which beam-like and reaction events separate, then tags reactions in it. The scatters and a reservoir of tagged events are cached, so retuning a display window or a region cut costs a reprojection rather than another pass over the data.

Enumeration Type Documentation

◆ PreCut

enum PreCut

The event-level cuts applied before any reaction is asked about, in order; sequential like TagCut.

kPRE_PASS reached the tag.

Enumerator
kPRE_PASS
kPRE_ALL_STRIPS	A strip did not fire.
kPRE_GATE	Failed a beam gate.
kPRE_PILEUP	Pileup.
kPRE_NOISE	Noise.
kPRE_SMOOTH	A strip-to-strip step above SMOOTHNESS_NSIGMA.
kPRE_BOTH_MULT	Both-ends multiplicity (BOTH_MULT_MAX).
kNPRECUTS

Definition at line 120 of file StripSumScatter.hpp.

◆ TagCut

enum TagCut

The conditions of the reaction tag, in the order they are applied.

StripSumScatter::RejectReason returns the first one an event fails at a reaction strip, so the per-condition counts are sequential: each counts events that passed everything before it. kTAG_PASS is a tag.

Enumerator
kTAG_PASS
kCUT_UPSTREAM	A strip before the reaction was not beam-like.
kCUT_JUMP	Jump at the reaction strip below the gate.
kCUT_REAC_LEVEL	Reaction-strip deposit below 1 + the gate.
kCUT_TAIL_RISE	A rise in the tail (TAIL_RISE_NSIGMA).
kCUT_RERISE	Back at the beam, then above it again (TAIL_RERISE_*).
kCUT_POST_ABOVE	The excess did not persist (POST_ABOVE_*).
kCUT_CROSS	Read below the beam before POST_CROSS_MIN_STRIP.
kCUT_END_STRIP	The end strip not END_STRIP_NSIGMA below the beam.
kCUT_CLIFF	The fall happened in the last step (TAIL_CLIFF_*).
kCUT_OTHER_TAG	Passed, but the event's one tag went to another strip.
kNTAGCUTS
