UCAC1 mags for Brian's LONEOS ref stars [re WR 104] NOTE: unfortunately these reference stars ain't in the same UCAC field as WR104, but it is an immediately adjacent field. >Name RA (2000) Dec s GSC V B-V UCAC >NGC 6514 291 18 03 07.8 -23 05 50 G 6842-0020 10.23 0.06 10.28 >NGC 6514 331 18 03 18.6 -23 10 44 G 6842-1378 11.02 0.11 11.06 >NGC 6514 163 18 02 30.7 -23 09 06 G 6842-0599 11.64 -0.10 11.49 >NGC 6514 196 18 02 32.9 -23 06 31 G 6842-0593 12.29 0.15 12.08 >NGC 6514 160 18 02 29.9 -23 07 47 G 6842-0369 12.65 0.64 12.33 >NGC 6514 157 18 02 26.9 -23 05 42 G 6842-0060 13.15 0.56 n/a (see also http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/Mail/vsnet-newvar/829) I suppose USNO A2.0 "colours" could be used to select a subset of UCAC stars in the WR104 field that aren't too red, and then a local conversion routine assumed from the above???
