ModelBoundingBox#

class astropy.modeling.bounding_box.ModelBoundingBox(intervals: dict[int, _Interval], model, ignored: list[int] | None = None, order: str = 'C')[source]#

Bases: _BoundingDomain

A model’s bounding box.

Parameters:
intervalsdict
A dictionary containing all the intervals for each model input

keys -> input index values -> interval for that index

modelModel

The Model this bounding_box is for.

ignoredlist

A list containing all the inputs (index) which will not be checked for whether or not their elements are in/out of an interval.

orderoptional, str

The ordering that is assumed for the tuple representation of this bounding_box. Options: ‘C’: C/Python order, e.g. z, y, x. (default), ‘F’: Fortran/mathematical notation order, e.g. x, y, z.

Attributes Summary

dimension

intervals

Return bounding_box labeled using input positions.

Methods Documentation

bounding_box(order: str | None = None)[source]#
Return the old tuple of tuples representation of the bounding_box

order=’C’ corresponds to the old bounding_box ordering order=’F’ corresponds to the gwcs bounding_box ordering.

copy(ignored=None)[source]#
domain(resolution, order: str | None = None)[source]#
fix_inputs(model, fixed_inputs: dict, _keep_ignored=False)[source]#

Fix the bounding_box for a fix_inputs compound model.

Parameters:
modelModel

The new model for which this will be a bounding_box

fixed_inputsdict

Dictionary of inputs which have been fixed by this bounding box.

keep_ignoredbool

Keep the ignored inputs of the bounding box (internal argument only)

has_interval(key)[source]#
prepare_inputs(input_shape, inputs) tuple[Any, Any, Any][source]#

Get prepare the inputs with respect to the bounding box.

Parameters:
input_shapetuple

The shape that all inputs have be reshaped/broadcasted into

inputslist

List of all the model inputs

Returns:
valid_inputslist

The inputs reduced to just those inputs which are all inside their respective bounding box intervals

valid_indexarray_like

array of all indices inside the bounding box

all_out: bool

if all of the inputs are outside the bounding_box

classmethod validate(model, bounding_box, ignored: list | None = None, order: str = 'C', _preserve_ignore: bool = False, **kwargs)[source]#

Construct a valid bounding box for a model.

Parameters:
modelModel

The model for which this will be a bounding_box

bounding_boxdict, tuple

A possible representation of the bounding box

orderoptional, str
The order that a tuple representation will be assumed to be

Default: ‘C’
