Detailed Description

Findlet for combining CDC tracks with SVD tracks.

The idea is to use every fitted CDC track, extrapolate it to every SVD track and extrapolate/Kalman fit it with every hit of the track.

Then, a filter is applied to every CDC-SVD combination and the combinations are resolved using this filter information.

This module does only output relations - the combination has to be done afterwards.
