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().
