pixel_to_skycoord¶

astropy.wcs.utils.pixel_to_skycoord(xp, yp, wcs, origin=0, mode='all', cls=None)[source] [edit on github]¶

Convert a set of pixel coordinates into a SkyCoord coordinate.

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: The class of object to create. Should be a SkyCoord subclass. If None, defaults to SkyCoord.

Returns:

coords : Whatever cls is (a subclass of SkyCoord): The celestial coordinates
