a42548b0 7// Class for the fast simulation of the muon trigger efficiency
8// The trigger parametrization is computed for background levels 0., 0.5 and 1.
9// In order to set a background level different from 0 it is necessary to
10// explicitly force it with:
11// ForceBkgLevel(BkgLevel).
12// For intermediate background levels, the trigger response is linearly
13// interpolated between these values.
14// There is increased granularity in the pT region below 3 GeV. Although
15// it does not seem to be necessary it is also possible to interpolate
16// between pT bins using SetInt().
