Member Function Documentation

◆ appendRange() [1/3]

std::size_t appendRange ( const CDCSegment3D & segment3D )

Appends all reconstructed hits from the three dimensional segment.

Returns: Number of added hits

Definition at line 82 of file CDCSZObservations.cc.

 {
   const std::vector<CDCRecoHit3D> recoHit3Ds = segment3D;
   return this->appendRange(recoHit3Ds);
 }

◆ appendRange() [2/3]

std::size_t appendRange ( const CDCTrack & track )

Appends all reconstructed hits from the three dimensional track.

Returns: Number of added hits

Definition at line 88 of file CDCSZObservations.cc.

◆ appendRange() [3/3]

std::size_t appendRange ( const std::vector< CDCRecoHit3D > & recoHit3Ds )

Appends all reconstructed hits from the three dimensional track.

Returns: Number of added hits

Definition at line 73 of file CDCSZObservations.cc.

◆ fill()

std::size_t fill	(	double	s,
		double	z,
		double	weight = `1.0`
	)

Appends the observed position.

Note: Observations are skipped, if one of the given variables is NAN.

Parameters

s	S coordinate of the center of the observed position.
z	Z coordinate of the center of the observed position.
weight	The relative weight of the observation. In order to generate a unit less chi^2 measure the weight should be chosen as the inverse variance of the drift length. Defaults to 1.

Returns: Number of observations added. One if the observation was added. Zero if one of the given variables is NAN.
