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<class Transform>
std::shared_ptr<Transform> readStream(std::istream &is)

Deserialize a Transform from an input stream

Template Parameters

  • Transform: the Transform class; can be Transform<FromEndpoint, ToEndpoint>, SkyWcs, or any other compatible class, i.e. it must support the following (see Transform.h for details):

    • a constructor that takes an ast::FrameSet

    • static method getShortClassName

    • method getMapping

Parameters

  • [in] is: input stream from which to deserialize this Transform

template<class Transform>
void writeStream(Transform const &transform, std::ostream &os)

Serialize a Transform to an output stream

Version 1 format is as follows:

  • The version number (an integer)

  • A space

  • The short class name, as obtained from getShortClassName

  • A space

  • The contained ast::FrameSet written using FrameSet.show(os, false)

Parameters

  • [out] os: output stream to which to serialize this Transform

  • [in] transform: Transform to serialize

Variables

constexpr int serializationVersion = 1

version of serialization used when writing (older versions may also be supported when reading)
