Constructor & Destructor Documentation

◆ Associations() [1/3]

lsst::jointcal::Associations::Associations ( )
inline

Source selection is performed in python, so Associations' constructor only initializes a couple of variables.

Definition at line 43 of file Associations.h.

◆ Associations() [2/3]

lsst::jointcal::Associations::Associations ( Associations const &  )
delete

No moves or copies: jointcal only ever needs one Associations object.

◆ Associations() [3/3]

lsst::jointcal::Associations::Associations ( Associations &&  )
delete

Member Function Documentation

◆ addImage()

void lsst::jointcal::Associations::addImage ( lsst::afw::table::SortedCatalogT< lsst::afw::table::SourceRecord > &  catalog,
std::shared_ptr< lsst::afw::geom::SkyWcs wcs,
std::shared_ptr< lsst::afw::image::VisitInfo visitInfo,
lsst::afw::geom::Box2I const &  bbox,
std::string const &  filter,

std::shared_ptr< afw::cameraGeom::Detector detector,
int  visit,
int  ccd,
lsst::jointcal::JointcalControl const &  control 
)

Create a ccdImage from an exposure catalog and metadata, and add it to the list.

Parameters
[in]catalogThe extracted source catalog, selected for good astrometric sources.
[in]wcsThe exposure's original wcs
[in]visitInfoThe exposure's visitInfo object
[in]bboxThe bounding box of the exposure
[in]filterThe exposure's filter
[in]photoCalibThe exposure's photometric calibration
[in]detectorThe exposure's detector
[in]visitThe visit identifier
[in]ccdThe ccd identifier
[in]controlThe JointcalControl object

◆ associateCatalogs()

void lsst::jointcal::Associations::associateCatalogs ( const double  matchCutInArcsec = 0,
const bool  useFittedList = false,
const bool  enlargeFittedList = true 
)

incrementaly builds a merged catalog of all image catalogs

Definition at line 57 of file Associations.cc.

◆ collectRefStars()

void lsst::jointcal::Associations::collectRefStars ( lsst::afw::table::SortedCatalogT< lsst::afw::table::SimpleRecord > &  refCat,
afw::geom::Angle  matchCut,
std::string const &  fluxField,
std::map< std::string, std::vector< double >> const &  refFluxMap,
std::map< std::string, std::vector< double >> const &  refFluxErrMap,
bool  rejectBadFluxes = false 
)

Collect stars from an external reference catalog and associate them with fittedStars.

Parameters
refCatThe catalog of reference sources
[in]matchCutSeparation radius to match fitted and reference stars.
fluxFieldThe field name in refCat to get the flux from.
refFluxMapfluxes per filter of corresponding refCat objects (can be empty)
refFluxErrMapflux errors per filter of corresponding refCat objects (can be empty)
rejectBadFluxesReject reference sources with flux=NaN or 0 and/or fluxErr=NaN or 0. Typically false for astrometry and true for photometry.
