Detailed Description

Calculation of the Joint probability flavour tag inputs.

This class calculates the joint probability flavour tag input. This is the probability that all the tracks of a Jet come from the primary vertex. The calculation is done by using the information on the impact parameters of each Track. The class outputs three values : the calculation of joint probability in the RPhi plane, in the Z direction and in 3 dimensions. Please note that while the first two have been extensively tested the third has not since it is not used as a flavour tagging inputs parameter.

Parameters

MaxD0Significance	Maximum d0 significance. All more significant Tracks get cut.
MaxD0andZ0	Maximum value of d0 and of z0.
ResolutionParameterRphi	This is a Pointer parameter. It must point to a vector containing 5 double elements. These are the standard deviations of the impact parameter significances of the distribution of tracks coming from the primary vertex. These values can be obtained from a fit to the impact parameter distribution of tracks behind the interaction point, i.e. with negative impact parameter, where the direction of reference is the Jet direction. Please note that ideally these parameters should be calculated whenever the boundary conditions change in a way that affects the impact parameter distributions, by running a separate processor beforehand. This at the moment is not done and the values are inserted as parameters. The default values have been inherited from previous studies.
ResolutionParameterZ	Similar as ResolutionParameterRphi, but for the Z direction.
ResolutionParameter3D	Similar as before but for the 3-D calculation
