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.

Functions

template<typename ImagePixelT>
int copyGoodPixels(lsst::afw::image::Image<ImagePixelT> &destImage, lsst::afw::image::Image<ImagePixelT> const &srcImage)

copy good pixels from one image to another

Parameters

  • destImage: image to be modified

  • srcImage: image to copy

Good pixels are those that are not NaN (thus they do include +/- inf).

Only the overlapping pixels (relative to the parent) are copied; thus the images do not have to be the same size.

Return

number of pixels copied

template<typename ImagePixelT>
int copyGoodPixels(lsst::afw::image::MaskedImage<ImagePixelT, lsst::afw::image::MaskPixel, lsst::afw::image::VariancePixel> &destImage, lsst::afw::image::MaskedImage<ImagePixelT, lsst::afw::image::MaskPixel, lsst::afw::image::VariancePixel> const &srcImage, lsst::afw::image::MaskPixel const badPixelMask)

copy good pixels from one masked image to another

Parameters

  • destImage: image to be modified

  • srcImage: image to copy

  • badPixelMask: skip input pixel if src mask & badPixelMask != 0

Good pixels are those for which mask & badPixelMask == 0.

Only the overlapping pixels (relative to the parent) are copied; thus the images do not have to be the same size.

Return

number of pixels copied
