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.

namespace afw
namespace image
class MaskFitsReader : public lsst::afw::image::ImageBaseFitsReader
#include <MaskFitsReader.h>

A FITS reader class for Masks.

All MaskFitsReader methods provide strong exception safety, but exceptions thrown by the internal fits::Fits object itself may change its status variable or HDU pointer; MaskFitsReader guards against this by resetting those before any use of the Fits object.

Public Functions

template<typename PixelT>
Mask<PixelT> read(lsst::geom::Box2I const &bbox = lsst::geom::Box2I(), ImageOrigin origin = PARENT, bool conformMasks = false, bool allowUnsafe = false)

Read the Mask.

In Python, this templated method is wrapped with an additional

dtype argument to provide the type to read. This defaults to the type of the on-disk image.
Parameters

  • bbox: A bounding box used to defined a subimage, or an empty box (default) to read the whole image.

  • origin: Coordinate system convention for the given box.

  • conformMasks: If True, conform the global mask dict to match this file.

  • allowUnsafe: Permit reading into the requested pixel type even when on-disk values may overflow or truncate.
