Class CcdImage

Class Documentation

class CcdImage

Handler of an actual image from a single CCD. NOTE: could possibly be replaced with a subclass of afw.image.Exposure?

Unnamed Group

MeasuredStarList const &getCatalogForFit() const

Gets the catalog to be used for fitting, which may have been cleaned-up.

Return

The catalog for fitting.

MeasuredStarList &getCatalogForFit()

Public Functions

CcdImage(afw::table::SourceCatalog &record, std::shared_ptr<lsst::afw::geom::SkyWcs> wcs, std::shared_ptr<lsst::afw::image::VisitInfo> visitInfo, lsst::geom::Box2I const &bbox, std::string const &filter, std::shared_ptr<afw::image::PhotoCalib> photoCalib, std::shared_ptr<afw::cameraGeom::Detector> detector, int visit, int ccd, std::string const &fluxField)
CcdImage(CcdImage const&)

No move or copy: each CCD image is unique to that ccd+visit, and Associations holds all CcdImages.

CcdImage(CcdImage&&)
CcdImage &operator=(CcdImage const&)
CcdImage &operator=(CcdImage&&)
std::string getName() const

Return the _name that identifies this ccdImage.

MeasuredStarList const &getWholeCatalog() const

Gets the as-read catalog.

Return

The whole catalog.

void resetCatalogForFit()

Clear the catalog for fitting and set it to a copy of the whole catalog.

std::pair<int, int> countStars() const

Count the number of valid measured and reference stars that fall within this ccdImage.

Measured stars are counted if they are valid. Reference stars are counted if a measured star (valid or not) has a fittedStar that has an associated refStar.

Return

Number of (measured, reference) stars in the image.

void setCommonTangentPoint(Point const &commonTangentPoint)

Sets the common tangent point and computes necessary transforms.

Parameters

  • [in] commonTangentPoint: The common tangent point of all ccdImages (decimal degrees).

jointcal::Point const &getCommonTangentPoint() const

Gets the common tangent point, shared between all ccdImages.

Return

The common tangent point of all ccdImages (decimal degrees).

CcdIdType getCcdId() const

returns ccd ID

VisitIdType getVisit() const

returns visit ID

std::shared_ptr<afw::cameraGeom::Detector> getDetector() const
CcdImageKey getHashKey() const
double getAirMass() const

Airmass.

double getMjd() const

Julian Date.

std::shared_ptr<afw::image::PhotoCalib> getPhotoCalib() const

Return the exposure’s photometric calibration.

lsst::geom::SpherePoint getBoresightRaDec() const

Gets the boresight RA/Dec.

double getHourAngle() const
double getLstObs() const
double getSinEta() const

Parallactic angle.

double getCosEta() const

Parallactic angle.

double getTanZ() const

Parallactic angle.

Point getRefractionVector() const
std::string getFilter() const

return the CcdImage filter name

std::shared_ptr<AstrometryTransform> const getReadWcs() const

the wcs read in the header. NOT updated when fitting.

Frame const &getImageFrame() const

Frame in pixels.
