Definition Eigenstuff.h:38
LSST DM logging module built on log4cxx.
#define LOG_GET(logger)
Returns a Log object associated with logger.
Definition Log.h:75
Handler of an actual image from a single CCD.
Definition CcdImage.h:64
Base class for Chi2Statistic and Chi2List, to allow addEntry inside Fitter for either class.
Definition Chi2.h:44
A list of FittedStar s. Such a list is typically constructed by Associations.
Definition FittedStar.h:116
FitterBase(std::shared_ptr< Associations > associations)
Definition FitterBase.h:57
Sources measured on images.
A list of MeasuredStar. They are usually filled in Associations::createCcdImage.
void accumulateStatRefStars(Chi2Accumulator &accum) const override
Compute the chi2 (per star or total, depending on which Chi2Accumulator is used) for RefStars.
void assignIndices(std::string const &whatToFit) override
Set parameters to fit and assign indices in the big matrix.
void accumulateStatImageList(CcdImageList const &ccdImageList, Chi2Accumulator &accum) const override
Compute the chi2 (per star or total, depending on which Chi2Accumulator is used) for measurements.
PhotometryFit & operator=(PhotometryFit &&)=delete
PhotometryFit(PhotometryFit const &)=delete
No copy or move: there is only ever one fitter of a given type.
std::shared_ptr< PhotometryModel > getModel() const
Return the model being fit.
PhotometryFit & operator=(PhotometryFit const &)=delete
PhotometryFit(PhotometryFit &&)=delete
void leastSquareDerivativesReference(FittedStarList const &fittedStarList, TripletList &tripletList, Eigen::VectorXd &grad) const override
Compute the derivatives of the reference terms.
void getIndicesOfMeasuredStar(MeasuredStar const &measuredStar, IndexVector &indices) const override
this routine is to be used only in the framework of outlier removal
PhotometryFit(std::shared_ptr< Associations > associations, std::shared_ptr< PhotometryModel > photometryModel)
Construct a photometry fitter.
void saveChi2RefContributions(std::string const &filename) const override
Save a CSV file containing residuals of reference terms.
void leastSquareDerivativesMeasurement(CcdImage const &ccdImage, TripletList &tripletList, Eigen::VectorXd &grad, MeasuredStarList const *measuredStarList=nullptr) const override
Compute the derivatives of the measured stars and model for one CcdImage.
void saveChi2MeasContributions(std::string const &filename) const override
Save a CSV file containing residuals of measurement terms.
void offsetParams(Eigen::VectorXd const &delta) override
Offset the parameters by the requested quantities.
