! This example program is part of HiggsSignals (TS 26/09/2013).
!--------------------------------------------------------------------------------------
program HS_mass
! In this example the peak-centered chi^2 method is applied to a SM-like Higgs boson
! (overall signal strength scale factor mu) within the mass range 110 - 140 GeV.
! All three mass pdf choices are considered. Theoretical mass uncertainties and
! assignment range can be changed.
