Attributes Documentation

coord

The coordinate in a ComponentTree.

frame

The frame of this component

morph

Numpy view of the component morphology

sed

Numpy view of the component SED

shape

Shape of the image (Channel, Height, Width)

step_morph

step_sed

Methods Documentation

backward_prior()

Use the prior to update the gradient

display_model(observation=None, ax=None, filters=None, Q=10, stretch=1, show=True)

get_flux()

Get flux in every band

get_model(sed=None, morph=None, observation=None)

Get the model for this component.

Parameters

sed: array

An sed to use in the model. If sed is None then self.sed is used.

morph: array

A morphology to use in the model. If morph is None then self.morph is used.

Returns

model: array or tensor

(Bands, Height, Width) image of the model

modelToHeavy(filters, xy0=Point2I(0, 0), observation=None, dtype=<class 'numpy.float32'>)

Convert the model to a MultibandFootprint

morphToHeavy(peakSchema, xy0=Point2I(0, 0))

Convert the morphology to a HeavyFootprint

plot_history()

Plot the position and convergence history of an object

update()

Default update parameters for an ExtendedSource

This method can be overwritten if a different set of constraints or update functions is desired.
