The Reaction Filter Plugin

The basic concept of the Reaction Filter is to define a physics reaction (by you as the analyzer) in a configuration file which in turn will be used by the ReactionFilter plugin to create a Physics Analysis Root Tree (PART). This plugin applies primarily time, PID, and mass selection criteria and by default a Kinematic Fitter to the reconstructed charged track and/or neutral showers of each event based on the chosen reaction requirements.
