Rotation2D

class astropy.modeling.rotations.Rotation2D(angle=0.0, **kwargs)

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
inputs
outputs
param_names

Methods Summary

__call__(self, x, y[, 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.
