Class Acts::Experimental::Chi2Fitter

template<typename propagator_t, typename traj_t>
class Chi2Fitter

Chi2 fitter implementation.

Template Parameters

propagator_t – Type of the propagation class

Public Functions

inline Chi2Fitter(propagator_t pPropagator, std::unique_ptr<const Logger> _logger = getDefaultLogger("Chi2Fitter", Logging::INFO))

Fit implementation of the GX2F.


The input measurements are given in the form of SourceLink s. It’s the calibrators job to turn them into calibrated measurements used in the fit.

Template Parameters
  • source_link_iterator_t – Iterator type used to pass source links

  • start_parameters_t – Type of the initial parameters

  • parameters_t – Type of parameters used for local parameters

  • it – Begin iterator for the fittable uncalibrated measurements

  • end – End iterator for the fittable uncalibrated measurements

  • sParameters – The initial track parameters

  • chi2FitterOptions – Chi2FitterOptions steering the fit

  • trackContainer – The target track container


the output as an output track
