namespace lsst

Remove all non-astronomical counts from the Chunk Exposure’s pixels.

Class for a simple mapping implementing a generic AstrometryTransform.

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.

Forward declarations for lsst::utils::Cache

For details on the Cache class, see the Cache.h file.

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 utils

Functions

template<typename T>
constexpr void assertValidHash()

Compile-time test of whether a specialization of std::hash conforms to the general spec.

The function itself is a no-op.

Template Parameters

• T: The properties of std::hash<T> will be tested.

template<typename T>
void assertHashesEqual(T obj1, T obj2)

Test that equal objects have equal hashes.

If objects of type T can be equal despite having different internal representations, you should include pairs of such objects.

Template Parameters

• T: A hashable type.

Parameters

• obj1obj2: Two equal objects.
