Public Attributes
Int_t	reac = -1
	Reaction strip index; -1 for an unset record.
Double_t	n_counted = 0.0
	The numerator this efficiency belongs to: the events counted at this strip by the same selection the efficiency was measured for.
Double_t	eff = 0.0
	Fraction of true reactions at this strip that end up in n_counted.
Double_t	eff_err = 0.0
	Uncertainty on eff, or 0 when the method provides none.
Double_t	migrate = 0.0
	Fraction of true reactions at this strip counted at strip reac + 1 instead, which the cross section unfolds.
Double_t	tag_eff = 0.0
	Of eff, the part the tag alone passes; the remainder is the region cut.

Detailed Description

One channel and strip's efficiency, as the cross section consumes it.

The whole contract between the two sides. See the file overview for the formula these feed.

eff

Double_t TagEfficiencyRecord::eff = 0.0

Fraction of true reactions at this strip that end up in n_counted.

Definition at line 46 of file TagEfficiency.hpp.

Referenced by TagEfficiencyStore::Load(), and TagEfficiencyStore::Write().

eff_err

Double_t TagEfficiencyRecord::eff_err = 0.0

Uncertainty on eff, or 0 when the method provides none.

Definition at line 48 of file TagEfficiency.hpp.

Referenced by TagEfficiencyStore::Load(), and TagEfficiencyStore::Write().

migrate

Double_t TagEfficiencyRecord::migrate = 0.0

Fraction of true reactions at this strip counted at strip reac + 1 instead, which the cross section unfolds.

Definition at line 51 of file TagEfficiency.hpp.

Referenced by TagEfficiencyStore::Load(), and TagEfficiencyStore::Write().

n_counted

Double_t TagEfficiencyRecord::n_counted = 0.0

The numerator this efficiency belongs to: the events counted at this strip by the same selection the efficiency was measured for.

Pairing an efficiency with a differently-selected count is the error this field exists to prevent.

reac

Int_t TagEfficiencyRecord::reac = -1

Reaction strip index; -1 for an unset record.

tag_eff

Double_t TagEfficiencyRecord::tag_eff = 0.0

Of eff, the part the tag alone passes; the remainder is the region cut.
