virtual class needed in the abstraction of the distortion model

a virtual (interface) class for geometric transformations.
Handler of an actual image from a single CCD.
Definition CcdImage.h:64
A multi-component model, fitting mappings for sensors and visits simultaneously.
ConstrainedAstrometryModel(ConstrainedAstrometryModel const &)=delete
No copy or move: there is only ever one instance of a given model (i.e. per ccd+visit)
ConstrainedAstrometryModel & operator=(ConstrainedAstrometryModel const &)=delete
ConstrainedAstrometryModel(CcdImageList const &ccdImageList, std::shared_ptr< ProjectionHandler const > projectionHandler, int chipOrder, int visitOrder)
std::size_t getTotalParameters() const override
Return the total number of parameters in this model.
ConstrainedAstrometryModel(ConstrainedAstrometryModel &&)=delete
void offsetParams(Eigen::VectorXd const &Delta) override
Dispaches the offsets after a fit step into the actual locations of parameters.
ConstrainedAstrometryModel & operator=(ConstrainedAstrometryModel &&)=delete
void freezeErrorTransform() override
From there on, measurement errors are propagated using the current transforms (and no longer evolve).
void print(std::ostream &out) const override
Print a string representation of the contents of this mapping, for debugging.
AstrometryTransform const & getVisitTransform(VisitIdType const &visit) const
Access to mappings.
AstrometryTransform const & getChipTransform(CcdIdType chip) const
Access to mappings.
const std::shared_ptr< AstrometryTransform const > getSkyToTangentPlane(CcdImage const &ccdImage) const override
The mapping of sky coordinates (i.e.
AstrometryMapping * findMapping(CcdImage const &ccdImage) const override
Return a pointer to the mapping associated with this ccdImage.
std::vector< VisitIdType > getVisits() const
Access to array of visits involved in the solution.
Eigen::Index assignIndices(std::string const &whatToFit, Eigen::Index firstIndex) override
Positions the various parameter sets into the parameter vector, starting at firstIndex.
std::shared_ptr< afw::geom::SkyWcs > makeSkyWcs(CcdImage const &ccdImage) const override
Make a SkyWcs that contains this model.
AstrometryMapping const * getMapping(CcdImage const &) const override
Mapping associated to a given CcdImage.
