This file contains the parameters for smearing the transverse momentum p of charged tracks according to the simple formula ?p/p 2 = a + b/psinpsin? . This method of smearing track parameters is
enabled by setting the MCFast class constructor argument simple=true. The file parameter ConstantTerm = a and the the the file parameter ThetaTerm = b . By default, the errors for the track angles and impact pararameters are taken from the files defined in TrackParameters.properties. However, the angle and impact parameter errors can be scaled relative to these default errors using the SimpleTrack.properties parameters TanLambdaErrorScale, PhiErrorScale, D0ErrorSCale and Z0ErrorScale.
