ConfigHelper

class jdaviz.core.helpers.ConfigHelper(app=None, verbosity='info')

Bases: glue.core.hub.HubListener

The Base Helper Class. Provides shared abstracted helper methods to the user.

Subclasses should set _default_configuration if they are meant to be used with a specific configuration.

Parameters

appApplication or None

The application object, or if None, creates a new one based on the default configuration for this helper.

verbosity{‘debug’, ‘info’, ‘warning’, ‘error’}

Verbosity of the application.

Attributes Summary

fitted_models

Returns the fitted model parameters.

Methods Summary

get_model_parameters([models, model_label, x, y])	Convert each parameter of model inside models into a coordinate that maps the model name and parameter name to a astropy.units.Quantity object.
get_models([models, model_label, x, y])	Loop through all models and output models of the label model_label.
load_data(data[, parser_reference])

Attributes Documentation

fitted_models

Returns the fitted model parameters.

Returns

parametersdict

dict of Quantity arrays, or None.

Methods Documentation

get_model_parameters(models=None, model_label=None, x=None, y=None)

Convert each parameter of model inside models into a coordinate that maps the model name and parameter name to a astropy.units.Quantity object.

Parameters

modelsdict

A dictionary where the key is a model name and the value is an astropy.modeling.CompoundModel object.

model_labelstr

Get model parameters for a particular model by inputting its label.

xint

The x coordinate of the model spaxels that will be returned from get_models.

yint

The y coordinate of the model spaxels that will be returned from get_models.

Returns

dict

a dictionary of the form {model name: {parameter name: [[astropy.units.Quantity]]}} for 3d models or {model name: {parameter name: astropy.units.Quantity}} where the Quantity object represents the parameter value and unit of one of spaxel models or the 1d models, respectively.

get_models(models=None, model_label=None, x=None, y=None)

Loop through all models and output models of the label model_label. If x or y is set, return model_labels of those (x, y) coordinates. If x and y are None, print all models regardless of coordinates.

Parameters

modelsdict

A dict of models, with the key being the label name and the value being an astropy.modeling.CompoundModel object. Defaults to fitted_models if no parameter is provided.

model_labelstr

The name of the model that will be found and returned. If it equals default, every model present will be returned.

xint

The x coordinate of the model spaxels that will be returned.

yint

The y coordinate of the model spaxels that will be returned.

Returns

selected_modelsdict

Dictionary of the selected models.
