Rotation2D

class astropy.modeling.rotations.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 or Quantity

Angle of rotation (if float it should be in deg).

Attributes Summary

angle
n_inputs
n_outputs
param_names

Methods Summary

__call__(self, \*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, angle) Rotate (x, y) about angle.
