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.

KernelPsf
: public lsst::afw::table::io::PersistableFacade<KernelPsf>, public lsst::meas::algorithms::ImagePsf - #include <KernelPsf.h>
A Psf defined by a Kernel.
Subclassed by lsst::meas::algorithms::DoubleGaussianPsf, lsst::meas::algorithms::PcaPsf, lsst::meas::algorithms::SingleGaussianPsf
Public Functions
-
KernelPsf
(afw::math::Kernel const &kernel, geom::Point2D const &averagePosition = geom::Point2D()) Construct a KernelPsf with a clone of the given kernel.
We clone the Kernel in the public constructor to ensure the Psf is immutable after construction (we don’t want someone with another copy of the Kernel to be able to modify the one held by the Psf).
Derived classes may use the protected constructor, which takes a shared_ptr to Kernel and does not copy it.
-
geom::Point2D
getAveragePosition
() const Return average position of stars; used as default position.
-
bool
isPersistable
() const Whether this object is persistable; just delegates to the kernel.

Protected Functions
-
lsst::meas::algorithms::KernelPsf::KernelPsf(PTR ( afw::math::Kernel ) kernel, geom::Point2D const & averagePosition = geom::Point2D())
Construct a KernelPsf with the given kernel; it should not be modified afterwards.
