Calculate the chisq for the given reference trajectory based on the hits currently registered through the DTrackFitter base class into the cdchits and fdchits vectors. This does not get called by the core part of the fitter, but is used, rather, to give an "independent" value of the chisq based only on a reference trajectory and the input hits. It is called after the fit to calculate the final chisq.

Remove elements from my_resiv that are not "good" according to the good_all list. The my_good and good_all vectors should be the same size. The number of "true" entries in my_good should be the size of the my_resiv vector. For entries in the my_good vector that are true, but have an entry in good_all that is false, the corresponding entry in my_resiv will be removed. The my_resiv matrix (which should be N x 1) will be resized upon exit. The my_good vector will be set equal to good_all upon exit also so that my_resiv and my_good stay in sync.

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.

This routine is called when the TRKFIT:LR_FORCE_TRUTH parameters is set to a non-zero value (e.g. -PTRKFIT:LR_FORCE_TRUTH=1 is passed on the command line). This is used only for debugging and only with Monte Carlo data.

This routine will adjust the left-right choice of each hit based on the current fit track (represented by rt), and the truth information contained in the the DMCTruthPoint objects. It assumes the hits in hinfo correspond to the track represented by rt.

Calculate the chi-squared for a track specified by state relative to the given reference trajectory. This is just a wrapper for ChiSq(DReferenceTrajectory rt, vector<const DCoordinateSystem> &wires, vector<DVector3> &shifts, vector<double> &errs, vector<double> &chisqv) that accepts the state vector and re-swims the trajectory.

Fit the track with starting parameters given in the first step of the reference trajectory rt. On return, the reference trajectory rt will represent the final fit parameters and chisq, Ndof, resiv, cov_meas, cov_muls, and cov_parm will be filled based on the fit results.

This determines the best fit of the track using the least squares method described by R. Mankel Rep. Prog. Phys. 67 (2004) 553-622 pg 565. Since it uses a linear approximation for the chisq dependance on the fit parameters, several calls may be required for convergence.
