Get the p value of the fit.

Virtual, because the fitter may use a different probability distribution.

Has anything in the Track been changed since the fit?

References trackHasChanged_.

bool genfit::FitStatus::isFitConverged ( bool  inAllPoints = true) const
inline

Did the fit converge (in all Points or only partially)?

Per default, this function will only be true, if all TrackPoints (with measurements) have been used in the fit, and the fit has converged.

If one or more TrackPoints have been skipped (e.g. plane could not be constructed or extrapolation to plane failed), but the fit otherwise met the convergence criteria, isFitConverged(false) will return true.

These are provided for the sake of the fitter, and their interpretation may vary. For the Kalman-derived fitters in particular, this corresponds to the backwards fit.
