Relates transfo(s) to their position in the fitting matrix and allows interaction with the transfo(s)...
STL class.
double transform(CcdImage const &ccdImage, MeasuredStar const &measuredStar, double instFlux) const override
Return the on-sky transformed flux for measuredStar on ccdImage.
STL class.
unsigned assignIndices(std::string const &whatToFit, unsigned firstIndex) override
Assign indices to parameters involved in mappings, starting at firstIndex.
Class for a simple mapping implementing a generic Gtransfo.
objects measured on actual images.

void computeParameterDerivatives(MeasuredStar const &measuredStar, CcdImage const &ccdImage, Eigen::VectorXd &derivatives) const override
Compute the parametric derivatives of this model.
void dump(std::ostream &stream=std::cout) const override
Dump the contents of the transfos, for debugging.
void offsetParams(Eigen::VectorXd const &delta) override
Offset the parameters by the provided amounts.
Interface class for PhotometryFit.
Photometry model with constraints, .
double transformError(CcdImage const &ccdImage, MeasuredStar const &measuredStar, double instFluxErr) const override
Return the on-sky transformed flux uncertainty for measuredStar on ccdImage.
std::shared_ptr< afw::image::PhotoCalib > toPhotoCalib(CcdImage const &ccdImage) const override
Return the mapping of ccdImage represented as a PhotoCalib.
Handler of an actual image from a single CCD.

ConstrainedPhotometryModel(CcdImageList const &ccdImageList, afw::geom::Box2D const &focalPlaneBBox, int visitDegree=7)
Construct a constrained photometry model.

STL class.
void freezeErrorTransform() override
Once this routine has been called, the error transform is not modified by offsetParams().
void getMappingIndices(CcdImage const &ccdImage, std::vector< unsigned > &indices) const override
Get how this set of parameters (of length Npar()) map into the "grand" fit.
