Detail of Scorpius (see Fig. B.30) showing the relative positions of P 559 and P 560 (red) and the open cluster NGC 6231 (black Λ), together with the double star HIP 82729/HIP 82671 (open circles). A red circle marked 559′ denotes the position of P 559 when its latitude is corrected from  −18° to  −19°. HIP 82729 is a high-proper-motion star: the black • shows the position one would find for  −128 if proper motion is ignored. Solid lines indicate our identifications, the dash-dotted lines those by Ashworth (1981).
