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.

namespace jointcal

class IdentityProjectionHandler : public lsst::jointcal::ProjectionHandler

#include <ProjectionHandler.h>

The simplest implementation of ProjectionHandler. Means that coordinates of objects are expressed in the same space as the arrival mapping space. This is useful for fitting transform rms between images.

Public Functions

const std::shared_ptr<const AstrometryTransform> getSkyToTangentPlane(const CcdImage &ccdImage) const

Private Members

std::shared_ptr<AstrometryTransformIdentity> id

class OneTPPerVisitHandler : public lsst::jointcal::ProjectionHandler

#include <ProjectionHandler.h>

A projection handler in which all CCDs from the same visit have the same tangent point.

We arbitrarily chose that all chips from a same visit have the same tangent point.

Public Functions

OneTPPerVisitHandler(const CcdImageList &ccdImageList)

const std::shared_ptr<const AstrometryTransform> getSkyToTangentPlane(const CcdImage &ccdImage) const

Private Types

typedef std::map<const VisitIdType, std::shared_ptr<const AstrometryTransform>> TransformMap

Private Members

TransformMap tMap

struct ProjectionHandler

#include <ProjectionHandler.h>

This is a virtual class that allows a lot of freedom in the choice of the projection from “Sky” (where coodinates are reported) to tangent plane (where they are compared to transformed measurements)

Subclassed by lsst::jointcal::IdentityProjectionHandler, lsst::jointcal::OneTPPerVisitHandler

Public Functions

virtual const std::shared_ptr<const AstrometryTransform> getSkyToTangentPlane(const CcdImage &ccdImage) const = 0
