Detailed Description

A Parametric model for the integral of a 2D distribution.

IntegralModel implementations can use as many Parameter classes as needed. The model should be efficiently differentiable in the first order, via finite differencing if analytical evaluation is not possible.

IntegralModels may have meaningful ordering of channels but must enforce uniqueness constraints where relevant.

get_channels()

virtual std::vector< std::reference_wrapper< const Channel > > lsst::gauss2d::fit::Chromatic::get_channels ( ) const

pure virtualinherited

Get the set of channels this instance is applicable for.

Implementers must return a set (all unique items). This cannot be enforced (yet).

Implemented in lsst::gauss2d::fit::Data< T, I, M >, lsst::gauss2d::fit::FractionalIntegralModel, lsst::gauss2d::fit::LinearIntegralModel, and lsst::gauss2d::fit::SersicModelIntegral.

pure virtual

Get the value of the integral in a single Channel.

Implemented in lsst::gauss2d::fit::FractionalIntegralModel, lsst::gauss2d::fit::LinearIntegralModel, and lsst::gauss2d::fit::SersicModelIntegral.

get_integral_derivative_factors()

pure virtual

Return the partial derivative of the model w.r.t.

each metaparameter.

This is generally needed only for nonlinear Parameter instances.

Parameters

channel

The Channel to return derivatives for.

Returns

A vector of Parameter/derivative pairs, with values ordered as specified in GaussianEvaluator (L, sigma_x, sigma_y).

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.
