◆ computeParameterDerivatives()

virtual void lsst::jointcal::PhotometryMappingBase::computeParameterDerivatives ( MeasuredStar const &  measuredStar,
double  instFlux,
Eigen::Ref< Eigen::VectorXd >  derivatives 
) const
pure virtual

Compute the derivatives with respect to the parameters (i.e.

the coefficients).

Parameters
[in]measuredStarThe measured star position to transform.
[in]instFluxThe instrument flux to compute the derivative at.
[out]derivativesThe computed derivatives, in the same order as the deltas in offsetParams.

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.

◆ dump()

virtual void lsst::jointcal::PhotometryMappingBase::dump ( std::ostream stream = std::cout) const
pure virtual

Dump the contents of the transfos, for debugging.

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.

◆ getIndex()

unsigned lsst::jointcal::PhotometryMappingBase::getIndex ( )
inline

Get the index of this mapping in the grand fit.

Definition at line 80 of file PhotometryMapping.h.

◆ getMappingIndices()

virtual void lsst::jointcal::PhotometryMappingBase::getMappingIndices ( std::vector< unsigned > &  indices) const
pure virtual

Gets how this set of parameters (of length getNpar()) map into the "grand" fit.

Expects that indices has enough space reserved.

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.

◆ getNpar()

virtual unsigned lsst::jointcal::PhotometryMappingBase::getNpar ( ) const
pure virtual

Number of total parameters in this mapping.

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.

◆ getParameters()

inline

Definition at line 66 of file PhotometryMapping.h.

◆ offsetParams()

virtual void lsst::jointcal::PhotometryMappingBase::offsetParams ( Eigen::VectorXd const &  delta)
pure virtual

Offset the transfo parameters by delta.

Parameters
[in]deltavector to offset transfo parameters. Same ordering as derivatives in computeParameterDerivatives();

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.

◆ setFixed()

void lsst::jointcal::PhotometryMappingBase::setFixed ( bool  _fixed)
inline

Make this mapping's parameters fixed (i.e. not varied during fitting).

Definition at line 65 of file PhotometryMapping.h.

◆ setIndex()

void lsst::jointcal::PhotometryMappingBase::setIndex ( unsigned  i)
inline

Set the index of this mapping in the grand fit.

Definition at line 83 of file PhotometryMapping.h.

◆ transform()

virtual double lsst::jointcal::PhotometryMappingBase::transform ( MeasuredStar const &  measuredStar,
double  instFlux 
) const
pure virtual

Return the on-sky transformed flux at (x,y).

Parameters
[in]measuredStarThe measured star position to transform.
[in]instFluxThe instrument flux to transform.
Returns
The on-sky flux transformed from instFlux at measuredStar's position.

Implemented in lsst::jointcal::ChipVisitPhotometryMapping, and lsst::jointcal::PhotometryMapping.
