◆ computeParameterDerivatives()

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

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.

Implements lsst::jointcal::PhotometryMappingBase.

Definition at line 13 of file PhotometryMapping.cc.

◆ dump()

void lsst::jointcal::ChipVisitPhotometryMapping::dump ( std::ostream stream = std::cout) const
inlineoverridevirtual

Dump the contents of the transfos, for debugging.

Implements lsst::jointcal::PhotometryMappingBase.

inline

Definition at line 200 of file PhotometryMapping.h.

◆ getIndex()

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

Get the index of this mapping in the grand fit.

Definition at line 80 of file PhotometryMapping.h.

◆ getMappingIndices()

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

◆ offsetParams()

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

Definition at line 177 of file PhotometryMapping.h.

◆ setFixed()

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

Definition at line 65 of file PhotometryMapping.h.

◆ setIndex()

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

Set the index of this mapping in the grand fit.

Definition at line 83 of file PhotometryMapping.h.

◆ transform()

double lsst::jointcal::ChipVisitPhotometryMapping::transform ( MeasuredStar const &  measuredStar,
double  instFlux 
) const
inlineoverridevirtual

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.
