Rotation2D
(angle=Parameter('angle', value=0.0), **kwargs)[source]¶ Bases:
astropy.modeling.Model
Perform a 2D rotation given an angle.
Positive angles represent a counter-clockwise rotation and vice-versa.
- Parameters
- angle
float
orQuantity
[:ref: ‘angle’] Angle of rotation (if float it should be in deg).
- angle
Attributes Summary
The number of inputs.
The number of outputs.
Names of the parameters that describe models of this type.
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.

param_names
= ('angle',)¶ 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
Parameter
attributes defined in the class body.
