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(). | |
