Detailed Description

Perform linear fit and hits update for DT segments. Update a segment by improving the hits thanks to the refined knowledge of impact angle and position (also along the wire) and perform linear fit on improved hits.

do the linear fit on the hits of the segment candidate and update it. Returns false if the segment candidate is not good()

Definition at line 215 of file DTSegmentUpdator.cc.

void DTSegmentUpdator::fit	(	DTRecSegment2D *	seg,
		bool	allow3par,
		bool	block3par
	)		const

ditto for true segment: since the fit is applied on a true segment, by definition the segment is "good", while it's not the case for just candidates

Definition at line 279 of file DTSegmentUpdator.cc.

void DTSegmentUpdator::fit	(	DTRecSegment4D *	seg,
		bool	allow3par
	)		const

ditto for true segment 4D, the fit is done on either projection and then the 4D direction and position is built. Since the fit is applied on a true segment, by definition the segment is "good", while it's not the case for just candidates
