Detailed Description

A 2D Gaussian with a Centroid, Ellipse, and integral.

Gaussian offers some convenience functions but is otherwise a container for its three component subclasses.

Constructor & Destructor Documentation

Gaussian()

lsst::gauss2d::Gaussian::Gaussian ( std::shared_ptr< Centroid > centroid = nullptr, std::shared_ptr< Ellipse > ellipse = nullptr, std::shared_ptr< GaussianIntegral > integral = nullptr )

explicit

Construct a new Gaussian object.

Parameters

centroid	The centroid. Defaults to a new, default Centroid.
ellipse	The ellipse. Defaults to a new, default Ellipse.
integral	The integral. Defaults to a new, default GaussianIntegralValue.

repr()

std::string lsst::gauss2d::Gaussian::repr ( bool name_keywords = false, std::string_view namespace_separator = Object::CC_NAMESPACE_SEPARATOR ) const

overridevirtual

Return a full, callable string representation of this.

Parameters

name_keywords	Whether to prefix arguments with "{name}=", where name is the arg name in the header (as with keyword arguments in Python).
namespace_separator	The string to use to delimit namespaces, i.e. :: in C++ and . in Python.

Returns

A callable string representation of this, which should return an an identical object to this.

Note

The representation with name_keywords=false must be callable in C++. The representation with name_keywords=true should be callable in Python, if there are any bindings.
