Detailed Description

A set of parameters for the CA Track finder iteration.

Each iteration utilizes special physics cuts and run condition to find tracks of a particular class (e.g., fast primary tracks or secondary electron tracks). Hits associated with tracks reconstructed during current iteration are removed from the further iterations.
