Rotation2D

class astropy.modeling.rotations.Rotation2D(angle=0.0)

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
n_inputs	int(x[, base]) -> integer
n_outputs	int(x[, base]) -> integer
param_names	list() -> new empty list

Methods Summary

__call__(x, y)	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.
inverse()	Inverse rotation.
