code: def query(self, coords, order=1):
          
          return super(PG2010Query, self).query(coords, order=order)
docs: 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`.
