Parameters:

• x (numpy.ndarray) – Cartesian coordinates of points on the unit sphere.

• y (numpy.ndarray) – Cartesian coordinates of points on the unit sphere.

• z (numpy.ndarray) – Cartesian coordinates of points on the unit sphere.

Returns:

east, north (tuple of numpy.ndarray) – Local east and north unit vectors, each with shape (3, nPoints).
