struct hash<lsst::jointcal::CcdImageKey>

#include <CcdImage.h>

Hash a ccdImage by its visit and ccd IDs.

ccdId and visitId are both 32-bit ints, hash() returns a size_t, so put the ccdId in the most-significant-bit, and the visitId in the least for a simple, unique, hash per ccdImage.

Public Functions

size_t operator()(lsst::jointcal::CcdImageKey const &key) const

namespace lsst

Class for a simple mapping implementing a generic AstrometryTransform.

Remove all non-astronomical counts from the Chunk Exposure’s pixels.

Forward declarations for lsst::utils::Cache

For details on the Cache class, see the Cache.h file.

It uses a template rather than a pointer so that the derived classes can use the specifics of the transform. The class simplePolyMapping overloads a few routines.

A base class for image defects

Numeric constants used by the Integrate.h integrator routines.

Compute Image Statistics

Note

Gauss-Kronrod-Patterson quadrature coefficients for use in quadpack routine qng. These coefficients were calculated with 101 decimal digit arithmetic by L. W. Fullerton, Bell Labs, Nov 1981.

Note

The Statistics class itself can only handle lsst::afw::image::MaskedImage() types. The philosophy has been to handle other types by making them look like lsst::afw::image::MaskedImage() and reusing that code. Users should have no need to instantiate a Statistics object directly, but should use the overloaded makeStatistics() factory functions.

Functions

class CcdImage

#include <CcdImage.h>

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.

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).
