The ten stars measured by M&V in the starcloud Collinder 271 are given in SIMBAD variously with precise or approximate coordinates; the photometry is present, however. The group center is uncertain by as much as half an arcminute, so I leave my previous center determination unchanged. ------------------------------------------------------------------------------- Coordinates and identifications for stars in Collinder 271 version: 5 Jan 2002 source: 1973A&AS...10..135M cluster center: 13 30 00 -64 11.0 (J2000) (+/-0'.5) position sources (column 's'): G GSC-ACT (1999GSCTy.C......0G, I/255) g GSC-2.2 (2001GSC2..C......0S, I/271) T Tycho-2 (2000A&A...357..367H, I/259) U UCAC1 (2000AJ....120.2131Z, I/268) ID RA (J2000) Dec s GSC Tycho-2 V remarks 1 13 29 58.85 -64 14 29.9 T 8999-2796 8999-2796-1 9.5 HD 117135 2 13 30 16.63 -64 15 24.0 U 8999-0896 8999- 896-1 11.4 CPD-63 2784 3 13 30 17.27 -64 14 48.4 U 8999-1618 8999-1618-1 11.8 4 13 29 57.88 -64 13 11.4 U 8999-0350 8999- 350-1 11.8 5 13 29 49.00 -64 12 56.3 U 8999-2510 8999-2510-1 12.1 6 13 29 59.38 -64 11 33.2 U 8999-0206 8999- 206-1 11.3 CPD-63 2782 7 13 30 09.13 -64 11 39.1 g 12.5 8 13 30 03.80 -64 10 25.0 U 8999-0831 8999- 831-1 12.4 9 13 29 27.82 -64 11 07.1 U 8999-1452 8999-1452-1 12.1 10 13 29 37.65 -64 10 23.9 G 8999-2732 11.7
