V/122       SB9: 9th Catalogue of Spectroscopic Binary Orbits  (Pourbaix+ 2005)

The Ninth Catalogue of Spectroscopic Binary Orbits (Version September 2005) Pourbaix D., Tokovinin A.A, Batten A.H., Fekel F.C., Hartkopf W.I., Levato H., Morell N.I., Torres G., Udry S. <Astron. Astrophys. 424, 727 (2004)> =2004A&A...424..727P
ADC_Keywords: Binaries, orbits ; Binaries, spectroscopic Keywords: stars: binaries: spectroscopic - astronomical data bases: miscellaneous - catalogs Abstract: The Ninth Catalogue of Spectroscopic Binary Orbits continues the series of compilations of spectroscopic orbits carried out over the past 35 years by Batten and collaborators (see e.g. Cat. V/64). The catalogue is continuously updated, see http://sb9.astro.ulb.ac.be/ This version is dated 07 September 2005. The previous version may be found in the "v00" subdirectory. File Summary:

Note (1): the symbol '>' indicates that the error is large (larger than the value); the symbol 'a' indicates that the value was not computed, but assumed. Note (2): a non-zero value indicates that T0 does not correspond to the pariastron epoch, but to some other phenomena (e.g. eclipse)
