Find the hits for the track indicated by the given reference trajectory using truth points.

This will look through the list of charged tracks in DMCThrown and find the thrown track that most closely matches the starting parameters in "rt". Then, it will look through the DCDCTrackHit objects in cdchits_in and attempt to match them up with CDC hits in the DMCTrackHit objects. In this way, truth information can be used to generate a list of the CDC hits that belong with "rt".

static

Identify the DMCTrackHit object (if any) that best matches a hit on a given wire with a given drift distance.

This is static function and so can be used outside of this class. As such, the list of DMCTrackHits must be supplied by the caller. Also, the trackno_filter parameter is optional for use on checking only hits originating from a specific thrown track.
