Member Data Documentation

Chisq_Constrainer_Args hitfit::Fourvec_Constrainer_Args::_chisq_constrainer_args

private

The internal arguments for the subobjects.

Definition at line 180 of file Fourvec_Constrainer.h.

Referenced by chisq_constrainer_args().

double hitfit::Fourvec_Constrainer_Args::_e_com

private

The center-of-mass energy. Used only to keep the fit from going into a completely unphysical region.

Definition at line 166 of file Fourvec_Constrainer.h.

Referenced by e_com().

bool hitfit::Fourvec_Constrainer_Args::_ignore_met

private

If TRUE and the event does not have a neutrino, then the fit will be done without the overall transverse momentum constraint. Thus the missing transverse energy information will be ignored. If the event does have a neutrino, this parameter is ignored. If FALSE, take into account the overall transverse momentum constraint.

bool hitfit::Fourvec_Constrainer_Args::_use_e

private

If TRUE, then when rescaling a four-momentum for a given mass, keep the measured energy and scale the three-momentum. If FALSE, then keep the three-momentum and scale the energy.
