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.

Ellipse
- #include <Ellipse.h>
An ellipse defined by an arbitrary BaseCore and a center point.
An ellipse is composed of its center coordinate and its Core - a parametrization of the ellipticity and size of the ellipse. Setting the core of an ellipse never changes the type of the contained core, it merely sets the parameters of that core by converting the parameters.
Coordinate transforms
These member functions transform the ellipse by the given lsst::geom::AffineTransform. The transform can be done in-place by calling inPlace() on the returned expression object, or returned as a new shared_ptr by calling copy().

(lsst::geom::Point2D const ¢er) Set the center point.
-
BaseCore const &
getCore
() const Return the ellipse core.
-
BaseCore &
getCore
() Return the ellipse core.
-
void
setCore
(BaseCore const &core) Set the ellipse core; the type of the core is not changed.
-
void
normalize
() Put the parameters in a standard form.
-
void
grow
(double buffer) Increase the major and minor radii of the ellipse by the given buffer.
-
void
scale
(double factor) Scale the size of the ellipse by the given factor.
-
void
shift
(lsst::geom::Extent2D const &offset) Move the ellipse center by the given offset.
-
ParameterVector const
getParameterVector
() const Return the ellipse parameters as a vector.
-
void
setParameterVector
(ParameterVector const &vector) Set the ellipse parameters from a vector.

-
Ellipse::GridTransform const
getGridTransform
() const Return the transform that maps the ellipse to the unit circle.
The returned proxy object is implicitly convertible to lsst::geom::AffineTransform and also supports differentiation.
-
lsst::geom::Box2D
computeBBox
() const Return the bounding box of the ellipse.
-
Ellipse &
operator=
(Ellipse const &other) Set the parameters of this ellipse from another.
This does not change the parametrization of the ellipse.
-
bool
operator==
(Ellipse const &other) const Compare two ellipses for equality.
Ellipses are only equal if they have the same Core types.
-
bool
operator!=
(Ellipse const &other) const Compare two ellipses for inequality.
Ellipses are only equal if they have the same Core types.
