class Transformer

#include <Transformer.h>

A temporary-only expression object for ellipse core transformations.

Transformer simply provides a clean syntax for transform-related operations, including in-place and new-object transformations, derivatives of the transformations, and implicit conversion to a shared_ptr to a new transformed core.

Public Types

typedef Eigen::Matrix3d DerivativeMatrix

Matrix type for derivative with respect to input ellipse parameters.

typedef Eigen::Matrix<double, 3, 4> TransformDerivativeMatrix

Matrix type for derivative with respect to transform parameters.

Public Functions

Transformer(BaseCore &input_, lsst::geom::LinearTransform const &transform_)

Standard constructor.

std::shared_ptr<BaseCore> copy() const

Return a new transformed ellipse core.

void inPlace()

Transform the ellipse core in-place.

void apply(BaseCore &result) const

DerivativeMatrix d() const

Return the derivative of transformed core with respect to input core.

TransformDerivativeMatrix dTransform() const

Return the derivative of transformed core with respect to transform parameters.

class Transformer

#include <Transformer.h>

A temporary-only expression object for ellipse transformations.

Transformer simply provides a clean syntax for transform-related operations, including in-place and new-object transformations, derivatives of the transformations, and implicit conversion to an auto_ptr to a new transformed ellipse.

Public Types

typedef Eigen::Matrix<double, 5, 5> DerivativeMatrix

Matrix type for derivative with respect to input ellipse parameters.

typedef Eigen::Matrix<double, 5, 6> TransformDerivativeMatrix

Matrix type for derivative with respect to transform parameters.

Public Functions

std::shared_ptr<Ellipse> copy() const

Return a new transformed ellipse.

void inPlace()

Transform the ellipse in-place.

void apply(Ellipse &other) const

DerivativeMatrix d() 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.
