Update on track finding in FDC
From GlueXWiki
The segment-based track-finding algorithm has been refined:
- I no longer rely on the refitting to determine the charge of the particle unless the individual segment information is ambiguous for those segments linked into candidates.
- The dip angle and vertex position are determined from either the most upstream segment or the result of the refit depending on which gives a vertex position closest to the center of the target.
- The track-matching cut from segment to segment is now momentum-dependent: .
