Rotation3DToGWA

class stdatamodels.jwst.transforms.Rotation3DToGWA(angles, axes_order, name=None)

Bases: Model

Perform a 3D rotation given an angle in degrees.

Positive angles represent a counter-clockwise rotation and vice-versa.

Initialize the model.

Parameters:

anglesarray-like

Angles of rotation in deg in the order of axes_order.

axes_orderstr

A sequence of ‘x’, ‘y’, ‘z’ corresponding to axis of rotation

Attributes Summary

angles
n_inputs
n_outputs
param_names	Names of the parameters that describe models of this type.
separable
standard_broadcasting

Methods Summary

__call__(*inputs[, model_set_axis, ...])	Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(x, y, z, angles)	Apply the rotation to a set of 3D Cartesian coordinates.

angles

n_inputs = 3

n_outputs = 3

param_names = ('angles',)

Names of the parameters that describe models of this type.

The parameters in this tuple are in the same order they should be passed in when initializing a model of a specific type. Some types of models, such as polynomial models, have a different number of parameters depending on some other property of the model, such as the degree.

When defining a custom model class the value of this attribute is automatically set by the ~astropy.modeling.Parameter attributes defined in the class body.

separable = False

standard_broadcasting = False

Methods Documentation

__call__(*inputs, model_set_axis=None, with_bounding_box=False, fill_value=nan, equivalencies=None, inputs_map=None, **new_inputs)

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

evaluate(x, y, z, angles)

Apply the rotation to a set of 3D Cartesian coordinates.

Parameters:

x, y, zarray-like

Cartesian coordinates

anglesarray-like

Angles of rotation in deg in the order of axes_order.

Returns:

x, y, zarray-like

Rotated Cartesian coordinates
