Package org.jlab.rec.alert.projections

Class TrackProjector

java.lang.Object
org.jlab.rec.alert.projections.TrackProjector
public class TrackProjector extends Object
The TrackProjector class projects ahdc tracks to the inner surfaces of the bar and wedges of the atof

Uses ahdc track bank information (for now position, momentum) Creates a TrackProjection for each track.

TO DO: - replace hardcoded values with database values. - magnetic field ? use swimmer tools? - charge ?
