Definition: Eigenstuff.h:33
virtual class needed in the abstraction of the distortion model
virtual void transformPosAndErrors(FatPoint const &where, FatPoint &outPoint) const =0
The same as above but without the parameter derivatives (used to evaluate chi^2)
virtual void computeTransformAndDerivatives(FatPoint const &where, FatPoint &outPoint, Eigen::MatrixX2d &H) const =0
Actually applies the AstrometryMapping and evaluates the derivatives w.r.t the fitted parameters.
virtual void offsetParams(Eigen::VectorXd const &delta)=0
Remember the error scale and freeze it.
virtual void getMappingIndices(IndexVector &indices) const =0
Sets how this set of parameters (of length Npar()) map into the "grand" fit Expects that indices has ...
virtual std::size_t getNpar() const =0
Number of parameters in total.
virtual void positionDerivative(Point const &where, Eigen::Matrix2d &derivative, double epsilon) const =0
The derivative w.r.t. position.
virtual void print(std::ostream &out) const =0
Print a string representation of the contents of this mapping, for debugging.
A Point with uncertainties.
Definition: FatPoint.h:34
A point in a plane.
Definition: Point.h:37
std::ostream & operator<<(std::ostream &stream, AstrometryMapping const &mapping)
A base class for image defects.
