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.

Represent a PSF as a circularly symmetrical Gaussian.

Public Functions

SingleGaussianPsf(int width, int height, double sigma)

Constructor for a SingleGaussianPsf.

Additional arguments are historical and ignored, and maybe be removed in the future.

Parameters

  • [in] width: Number of columns in realizations of the PSF at a point.

  • [in] height: Number of rows in realizations of the PSF at a point.

  • [in] sigma: Radius of the Gaussian.

PTR(afw::detection::Psf) const

Polymorphic deep copy; should usually unnecessary because Psfs are immutable.

PTR(afw::detection::Psf)

Return a clone with specified kernel dimensions.

double getSigma() const

Return the radius of the Gaussian.

bool isPersistable() const

Whether the Psf is persistable; always true.
