VizieR Online Data Catalog: The Alma catalogue of OB stars - II. (Pantaleoni+, 2021)
Abstract
In order to clean and update the previous catalogue presented in the paper I (Reed et al. 2003AJ....125.2531R), we cross matched it with Gaia DR2 (Cat. I/345) and apply selection criteria on distances, proper motion, parallaxes and magnitudes. It permits us to build the new version of the catalogue with a strong confidence including sub-classifications in 5 differents categories of OB stars such as likely massive stars (M), high/intermediate-mass stars (I), intermediate/low-mass stars (L), high-gravity stars (H) and extragalactic stars (E) (see section 2.1).
The results of the cleaning and classification process are presented in the form of a main catalogue in tablea1.dat lists our final sample of 15 662 objects and three supplements tablea2-4.dat lists respectively the 2427 stars excluded due to bad astrometry or colours, the 211 unmatched objects, and the 393 duplicates.
