Detailed Description

Check ok before reading anything; why says what went wrong when it is false.

◆ beam

Gauss2D RegionFit::beam

The beam-like population, pinned from its own core.

Definition at line 91 of file RegionCuts.hpp.

◆ has_reac

Bool_t RegionFit::has_reac = kTRUE

kFALSE for a beam-only fit, as used by the ridge-band region mode.

reac is then a copy of beam with zero amplitude, and nothing draws or counts it.

◆ n_beam

Double_t RegionFit::n_beam = 0.0

Events the mixture attributes to each component.

Where the island sits on the beam's tail, this is the count a person drawing a tight region gets, and what a geometric cut cannot give: the region's ellipse also holds whatever tail lies under it, and the beam's real tail is far heavier than its Gaussian, so no model subtraction recovers it.
