Compute the distance on the sphere from x2, y1 to x1, y1. Parameters ---------- x : `pandas.Series` X pixel coordinate. y : `pandas.Series` Y pixel coordinate. cd11 : `pandas.Series` [1, 1] element of the local Wcs affine transform. cd11 : `pandas.Series` [1, 1] element of the local Wcs affine transform. cd12 : `pandas.Series` [1, 2] element of the local Wcs affine transform. cd21 : `pandas.Series` [2, 1] element of the local Wcs affine transform. cd22 : `pandas.Series` [2, 2] element of the local Wcs affine transform. Returns ------- raDecTuple : tuple RA and dec conversion of x and y given the local Wcs. Returned units are in radians.
