Pulkovo compilation of radial velocities for 35495 stars in a common system.
Not Available
| Photoelectric radial velocities, Paper XVI 625 ninth-magnitude K0 stars in the six southern Clube Selected Areas
Paper XIII of this series presented radial velocities for 406 stars incertain of the Clube Selected Areas, a set of areas systematicallyarranged in Galactic coordinates. We now complete the survey byproviding the radial velocities, mostly obtained at the EuropeanSouthern Observatory (ESO), of 625 stars in the six southernmost Areas.Each star has been measured at least twice; the mean velocities havestandard errors typically of 0.2-0.3 km s-1. Additionalobservations made from Haute-Provence of many of the stars that areobservable from there have helped to identify, and in some instances tocharacterize, the ~70 spectroscopic binaries discovered in thisprogramme. The final results of the programme, complementing those givenin table 3 of Paper XIII, are summarized in Table 12, which presents themean velocities and velocity dispersions in the six southern Areas. Itis noted that the difference between Paper XIII and this one as regardsthe provenance of the radial velocities has led to a small difference inzero-points, which is discussed in Section 3 and needs to be taken intoaccount in any analysis of the combined data.
