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 MatchT>
afw::math::Statistics makeMatchStatistics(std::vector<MatchT> const &matchList, int const flags, afw::math::StatisticsControl const &sctrl = afw::math::StatisticsControl())

Compute statistics of the distance field of a match list

Parameters

  • [in] matchList: list of matchList between reference objects and sources; fields read:

    • distance: distance between source and reference object, in arbitrary units; the resulting statistics have the same units as distance

  • [in] flags: what to calculate; OR constants such as lsst::afw::math::MEAN, MEANCLIP, STDDEV, MEDIAN, defined in lsst/afw/math/Statitics.h’s Property enum

  • [in] sctrl: statistics configuration

template<typename MatchT>
afw::math::Statistics makeMatchStatisticsInPixels(afw::geom::SkyWcs const &wcs, std::vector<MatchT> const &matchList, int const flags, afw::math::StatisticsControl const &sctrl = afw::math::StatisticsControl())

Compute statistics of on-detector radial separation for a match list, in pixels

Parameters

  • [in] wcs: WCS describing pixel to sky transformation

  • [in] matchList: list of matchList between reference objects and sources; fields read:

    • first: reference object; only the coord is read

    • second: source; only the centroid is read

  • [in] flags: what to calculate; OR constants such as lsst::afw::math::MEAN, MEANCLIP, STDDEV, MEDIAN, defined in lsst/afw/math/Statitics.h’s Property enum

  • [in] sctrl: statistics configuration

template<typename MatchT>
afw::math::Statistics makeMatchStatisticsInRadians(afw::geom::SkyWcs const &wcs, std::vector<MatchT> const &matchList, int const flags, afw::math::StatisticsControl const &sctrl = afw::math::StatisticsControl())

Compute statistics of on-sky radial separation for a match list, in radians

Parameters

  • [in] wcs: WCS describing pixel to sky transformation

  • [in] matchList: list of matchList between reference objects and sources; fields read:

    • first: reference object; only the coord is read

    • second: source; only the centroid is read

  • [in] flags: what to calculate; OR constants such as lsst::afw::math::MEAN, MEANCLIP, STDDEV, MEDIAN, defined in lsst/afw/math/Statitics.h’s Property enum

  • [in] sctrl: statistics configuration
