◆ computeParameterDerivatives()

virtual void lsst::jointcal::PhotometryMappingBase::computeParameterDerivatives ( MeasuredStar const &  measuredStar,
double  value,
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]valueThe instrument flux or magnitude to compute the derivative at.
[out]derivativesThe computed derivatives, in the same order as the deltas in offsetParams.

Implemented in lsst::jointcal::ChipVisitMagnitudeMapping, lsst::jointcal::ChipVisitFluxMapping, and lsst::jointcal::PhotometryMapping.

◆ freezeErrorTransform()

virtual void lsst::jointcal::PhotometryMappingBase::freezeErrorTransform ( )
pure virtual

Once this routine has been called, the error transform is not modified by offsetParams().

The routine can be called when the mappings are roughly in place. After the call, the transformations used to propagate errors are no longer affected when updating the mappings. This allows an exactly linear fit, which can be necessary for some model+data combinations.

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

◆ getIndex()

Eigen::Index lsst::jointcal::PhotometryMappingBase::getIndex ( )
inline

Get the index of this mapping in the grand fit.

Definition at line 120 of file PhotometryMapping.h.

120 { return index; }

◆ getMappingIndices()

virtual void lsst::jointcal::PhotometryMappingBase::getMappingIndices ( IndexVector 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 std::size_t lsst::jointcal::PhotometryMappingBase::getNpar ( ) const
pure virtual

Number of total parameters in this mapping.

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

◆ getParameters()

virtual Eigen::VectorXd lsst::jointcal::PhotometryMappingBase::getParameters ( )

◆ isFixed()

delete

◆ print()

virtual void lsst::jointcal::PhotometryMappingBase::print ( std::ostream out) const
pure virtual

Print a string representation of the contents of this mapping, for debugging.

This string representation can be very verbose, as it contains all of the parameters of all of the transforms in this mapping.

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 100 of file PhotometryMapping.h.

100 { fixed = _fixed; }

◆ setIndex()

void lsst::jointcal::PhotometryMappingBase::setIndex ( Eigen::Index  i)
inline

Set the index of this mapping in the grand fit.

Definition at line 123 of file PhotometryMapping.h.

123 { index = i; }

◆ transform()

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

Return the on-sky transformed flux for measuredStar on ccdImage.

Parameters
[in]measuredStarThe measured star position to transform.
[in]valueThe instrument flux or magnitude to transform.
Returns
The on-sky value () transformed from value at measuredStar's position.

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

◆ transformError()

virtual double lsst::jointcal::PhotometryMappingBase::transformError ( MeasuredStar const &  measuredStar,
double  value,
double  valueErr 
) const
pure virtual

Return the on-sky transformed flux uncertainty for measuredStar on ccdImage.

Matches the underlying PhotometryTransform's transformError() until freezeErrorTransform() is called.

Parameters
[in]measuredStarThe measured star position to transform.
[in]valueThe flux or magnitude to transform.
[in]valueErrThe flux or magnitude uncertainty to transform.
Returns
The on-sky value transformed from value at measuredStar's position.

Implemented in lsst::jointcal::ChipVisitMagnitudeMapping, lsst::jointcal::ChipVisitFluxMapping, and lsst::jointcal::PhotometryMapping.
