Description:
 def pixel_to_icrs_coords(x, y, wcs):
 """ Convert pixel coordinates to ICRS Right Ascension and Declination. This is merely a convenience function to extract RA and Dec. from a `~astropy.coordinates.SkyCoord` instance so they can be put in separate columns in a `~astropy.table.Table`. Parameters x : float or array-like The x pixel coordinate. y : float or array-like The y pixel coordinate. wcs : `~astropy.wcs.WCS` The WCS transformation to use to convert from pixel coordinates to ICRS world coordinates. `~astropy.table.Table`. Returns ------- ra : `~astropy.units.Quantity` The ICRS Right Ascension in degrees. dec : `~astropy.units.Quantity` The ICRS Declination in degrees. """
