Detailed Description

represents a deflection of the track caused through multiple scattering in material.

This class is part of the ATLAS tracking EDM and holds the deflection angles wrt. to the track's theta and phi and their uncertainties. Like that it can be filled with the full estimated deflection or only the additional uncertainty on the momentum direction as it is used by Kalman-filter style track fits.
