mass<0 means get it from starting_params

Fit a DTrackCandidate using a given mass hypothesis.

This will perform a full wire-based and time-based fit using the given mass and starting from the given candidate. The given DReferenceTrajectory is used to swim the track numerous times during the various stages but will be left with the final time-based fit result. The JEventLoop given will be used to get the hits (CDC and FDC) and default DTrackHitSelector to use for the fit.

jerror_t DTrackFitterRiemann::FitCircle ( void  )

Riemann Circle fit: points on a circle in x,y project onto a plane cutting the circular paraboloid surface described by (x,y,x^2+y^2). Therefore the task of fitting points in (x,y) to a circle is transormed to the task of fitting planes in (x,y, w=x^2+y^2) space
