Rotation2D

class astropy.modeling.rotations.Rotation2D

Bases: astropy.modeling.Model

Perform a 2D rotation given an angle in degrees.

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

Parameters:

angle : float

angle of rotation in deg

Attributes Summary

angle
inputs
inverse	Inverse rotation.
outputs
param_names

Methods Summary

__call__(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)	Apply the rotation to a set of 2D Cartesian coordinates given as two lists–one for the x coordinates and one for a y coordinates–or a single coordinate pair.
