Member Function Documentation

computeTransformAndDerivatives()

void lsst::jointcal::TwoTransfoMapping::computeTransformAndDerivatives ( FatPoint const &  where, FatPoint &  outPoint, Eigen::MatrixX2d &  H  ) const

virtual

Actually applies the mapping and evaluates the derivatives w.r.t the fitted parameters.

This is grouped into a single call because for most models, evaluating the derivatives w.r.T parameters is not much longer than just transforming

Implements lsst::jointcal::Mapping.

Definition at line 37 of file TwoTransfoMapping.cc.

freezeErrorTransform()

void lsst::jointcal::TwoTransfoMapping::freezeErrorTransform

(

)

Currently not implemented.

Definition at line 94 of file TwoTransfoMapping.cc.

getMappingIndices()

void lsst::jointcal::TwoTransfoMapping::getMappingIndices ( std::vector< unsigned > &  indices ) const

virtual

Sets how this set of parameters (of length Npar()) map into the "grand" fit Expects that indices has enough space reserved.

Implements lsst::jointcal::Mapping.

Definition at line 20 of file TwoTransfoMapping.cc.

getNpar()

unsigned lsst::jointcal::TwoTransfoMapping::getNpar ( ) const

virtual

Number of parameters in total.

Implements lsst::jointcal::Mapping.

Definition at line 18 of file TwoTransfoMapping.cc.

getTransfo1()

Gtransfo const& lsst::jointcal::TwoTransfoMapping::getTransfo1 ( ) const

inline

access to transfos

Definition at line 48 of file TwoTransfoMapping.h.

getTransfo2()

Gtransfo const& lsst::jointcal::TwoTransfoMapping::getTransfo2 ( ) const

inline

access to transfos

Definition at line 51 of file TwoTransfoMapping.h.

offsetParams()

void lsst::jointcal::TwoTransfoMapping::offsetParams ( Eigen::VectorXd const &  delta )

inlinevirtual

Remember the error scale and freeze it.

Note

this routine is not used when fitting (the Model manages the mappings separately), but can be useful for debugging

Implements lsst::jointcal::Mapping.

Definition at line 42 of file TwoTransfoMapping.h.

operator=() [1/2]

TwoTransfoMapping& lsst::jointcal::TwoTransfoMapping::operator= ( TwoTransfoMapping const &  )

delete

operator=() [2/2]

TwoTransfoMapping& lsst::jointcal::TwoTransfoMapping::operator= ( TwoTransfoMapping &&  )

delete

positionDerivative()

void lsst::jointcal::TwoTransfoMapping::positionDerivative ( Point const &  where, Eigen::Matrix2d &  derivative, double  epsilon  ) const

virtual

Currently not implemented.

Implements lsst::jointcal::Mapping.

Definition at line 82 of file TwoTransfoMapping.cc.

transformPosAndErrors()

void lsst::jointcal::TwoTransfoMapping::transformPosAndErrors ( FatPoint const &  where, FatPoint &  outPoint  ) const

virtual

The same as above but without the parameter derivatives (used to evaluate chi^2)

Implements lsst::jointcal::Mapping.
