I have another pair of O stars in Centaurus to consider. HD RA 2000 DEC 2000 MK Spectrum V 101413 11:39:45.85 -63:28:40.1 O9.5 III 8.32 101436 11:39:49.96 -63:28:43.6 O7 7.60 101436 = NSV 18833 It is strange coincidence, that in the case of the HD101190/101223 pair, and the HD 101413/101436 pair, one star has the HD number similar to the one you are querying, but the _other_ star has the NSV number. Useful Hint: There is a "General Catalogue of O Stars", which should be on line at CDS. I have a paper copy of the first edition by G. Goy (1973) Astron. Astrophys. Suppl. 12, 277. This edition had 633 stars; later editions have a few more, no doubt.
