Parameters

xp, ypfloat or ndarray

The coordinates to convert.

wcs~astropy.wcs.WCS

The WCS to use for convert

originint

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').

Returns

coord~astropy.coordinates.SkyCoord

A new object with sky coordinates corresponding to the input xp and yp.
