Measured once from the data and stamped into the cache. Set before any tagging begins and read-only afterwards, which is what makes them safe to share across the worker threads without synchronisation.

Detailed Description

Builds the strip-sum scatters, tags reactions, and draws the results.

The entry point behind the strip-sum-scatter binary. Fills per-strip scatters from the events files, caches them alongside a reservoir of tagged events, and draws the regions and trace overlays.

Note

The cache carries a fingerprint of every configuration knob that changes its contents — filters, gates, strip spans — so editing any of them rebuilds it automatically on the next run. There is no cache-clearing step to remember.

Constructor & Destructor Documentation

StripSumScatter()

StripSumScatter::StripSumScatter

(

)

Construct with empty scatters and no cache loaded.

Definition at line 5 of file StripSumScatter.cpp.

~StripSumScatter()

StripSumScatter::~StripSumScatter

(

)

Frees the scatters and the reservoir.

Definition at line 22 of file StripSumScatter.cpp.

Member Function Documentation

CacheName()

TString StripSumScatter::CacheName ( )

static

Filename of the scatter cache for this configuration.

Note

compute-regions reads the same file, so the name is defined here and nowhere else.

Definition at line 350 of file StripSumScatter.cpp.

Referenced by main(), Run(), and TagEfficiency::Run().

JumpMin()

Double_t StripSumScatter::JumpMin ( Int_t reac )

static

Minimum jump for a tag: REAC_JUMP_NSIGMA * JumpSigma(reac).

Parameters

reac	Reaction strip index.

Definition at line 68 of file StripSumScatter.cpp.

Referenced by PassesReaction(), and Run().

JumpSigma()

Double_t StripSumScatter::JumpSigma ( Int_t strip )

static

Sigma of the strip-to-strip difference total[s] - total[s-1].

Parameters

strip

Strip index.

Definition at line 50 of file StripSumScatter.cpp.

Referenced by JumpMin().

PassesReaction()

Bool_t StripSumScatter::PassesReaction ( const EnergyView & ev, Int_t reac )

static

Whether an event is tagged as a reaction at a given strip.

Parameters

ev	Decoded event.
reac	Reaction strip index.

Returns

kTRUE if the event is tagged there.

Note

Public because TagEfficiency pushes bootstrapped traces through this same tag. An efficiency measured against a different selection than the one that produced the count would not apply to it.

Definition at line 181 of file StripSumScatter.cpp.

PlaneXY()

void StripSumScatter::PlaneXY ( const Double_t * total, Int_t reac, Double_t & x, Double_t & y )

static

Where an event sits in the scatter plane for a given reaction strip.

x is the sum over X_LO..X_HI; y is the sum over the post-trigger window.

Parameters

	total	Calibrated per-strip totals for the event.
	reac	Reaction strip index.
[out]	x	Plane x coordinate.
[out]	y	Plane y coordinate.

Note

Every consumer of a region cut goes through this, which is what stops the fill, the overlay and the cross section from ever disagreeing about where an event sits.

Definition at line 324 of file StripSumScatter.cpp.

Run()

void StripSumScatter::Run

(

)

Build or load the scatters, tag reactions, and draw everything.

void StripSumScatter::SetJumpSigma ( const Double_t * sigma )

static

Call before tagging starts.

Parameters

sigma

StripSigma()

Double_t StripSumScatter::StripSigma ( Int_t strip )

static

Sigma of a strip's own deposit.

Parameters

strip

Parameters

reac	Reaction strip index.

YLoOf()

Int_t StripSumScatter::YLoOf ( Int_t reac )

static

First strip of the post-trigger window summed onto y.

Parameters

reac	Reaction strip index.

Returns

The strip index, inclusive, per the POST_TRIGGER_SUM_STRIPS / POST_WINDOW_LAST_STRIP / POST_WINDOW_STRIPS rule.
