Detailed Description

Class storing the meta-data for track-vertex association: status, propagation distance, impact parameter, impact parameter error, chi2.

The status is meant to describe if and how the track was used in the vertex fit. The values of the parameters (propagation distance, impact parameter, impact parameter error, chi2) should be computed in an unbiased way, i.e. with respect to the vertex re-fitted without using the specific associated track. A method is also provided to retrieve the impact parameter significance.
