+// Class for the fast simulation of the muon trigger efficiency
+// The trigger parametrization is computed for background levels 0., 0.5 and 1.
+// In order to set a background level different from 0 it is necessary to 
+// explicitly force it with:
+// ForceBkgLevel(BkgLevel).
+// For intermediate background levels, the trigger response is linearly 
+// interpolated between these values.
+// There is increased granularity in the pT region below 3 GeV. Although
+// it does not seem to be necessary it is also possible to interpolate
+// between pT bins using SetInt().
+// Author: Pietro Cortese (Universita' del Piemonte Orientale - Alessandria 
+// and INFN of Torino)
