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 LhsT>
void for_each_pixel(Image<LhsT> &lhs, pixelOp0<LhsT> const &func)

Parameters

  • lhs: Image to set

  • func: functor to call

Set each pixel in an Image<LhsT> to func()

template<typename LhsT>
void for_each_pixel(Image<LhsT> &lhs, pixelOp1<LhsT> const &func)

Parameters

  • lhs: Image to set

  • func: functor to call

Set each pixel in an Image<LhsT> to func(lhs)

template<typename LhsT>
void for_each_pixel(Image<LhsT> &lhs, pixelOp1XY<LhsT> const &func)

Parameters

  • lhs: Image to set

  • func: functor to call

Set each pixel in an Image<LhsT> to func(x, y, lhs)

(x, y) allow for lhs.getXY0()

  • func: functor to call

Set each pixel in an Image<LhsT> to func(rhs), getting the rhs from an Image<RhsT>

template<typename LhsT, typename RhsT>
void for_each_pixel(Image<LhsT> &lhs, Image<RhsT> const &rhs, pixelOp2<LhsT, RhsT> const &func)

Parameters

  • func: functor to call

Set each pixel in an Image<LhsT> to func(lhs, rhs), getting the rhs from an Image<RhsT>

template<typename LhsT, typename RhsT>
void for_each_pixel(Image<LhsT> &lhs, Image<RhsT> const &rhs, pixelOp2XY<LhsT, RhsT> const &func)

Parameters

  • lhs: Image to set

  • rhs: other Image to pass to func

  • func: functor to call

Set each pixel in an Image<LhsT> to func(x, y, lhs, rhs), getting the rhs from an Image<RhsT>

(x, y) allow for lhs.getXY0()
