Methods Documentation

get_size_label() → str

Return the label for the component’s size parameters.

get_type_name() → str

Return a descriptive component name.

make_component(centroid: CentroidParameters, integral_model: IntegralModel) → ComponentData

Make a Component reflecting the current configuration.

Parameters

centroid

Centroid parameters for the component.

integral_model

The integral_model for this component.

Returns

component_data

An appropriate ComponentData including the initialized component.

Notes

The default gauss2d.fit.LinearIntegralModel can be populated with unit fluxes (gauss2d.fit.IntegralParameterD instances) to prepare for linear least squares fitting.
