Parameters:

xp, yp : float or numpy.ndarray

The coordinates to convert.

wcs : WCS

The WCS transformation to use.

origin : int

Whether to return 0 or 1-based pixel coordinates.

mode : ‘all’ or ‘wcs’

Whether to do the transformation including distortions ('all') or only including only the core WCS transformation ('wcs').

cls : class or None
