Returns the P&G (2010) correction to the SFD'98 E(B-V) at the specified
        location(s) on the sky. If component is 'err', then return the
        uncertainty in the correction.

        Args:
            coords (:obj:`astropy.coordinates.SkyCoord`): The coordinates to query.
            order (Optional[:obj:`int`]): Interpolation order to use. Defaults to ``1``,
                for linear interpolation.

        Returns:
            A float array containing the P&G (2010) correction (or its
            uncertainty) to SFD'98 at every input coordinate. The shape
            of the output will be the same as the shape of the coordinates
            stored by :obj:`coords`.
