- Аннотация: Table 1 lists the spectral, photometric and kinematic data for stars in OB-associations. It presents the name of a star, the name of the OB-association to which it is assigned by Blaha and Humphreys (1989AJ.....98.1598B), spectral type of the star, code of its luminosity class cL: 2 -- Ia, 4 -- Iab, 6 -- Ib, 8 -- II, 10 -- III, 12 -- IV, 14 -- V, where the corresponding odd numbers (1, 3,..., 13) reflect the uncertainty in its determination. It also gives the heliocentric distance to the OB-association by Blaha and Humphreys (1989AJ.....98.1598B), rBH, reduced to the short distance scale, r=0.8 rBH. Table 1 also lists Gaia DR2 data (2018, Cat. I/345/gaia2) (2018A&A...616A...1G): the equatorial coordinates of the star, its Galactic coordinates, the G-band magnitude, the parallax, proper motions along the l- and b-directions and their errors. It also presents the number of visibility periods, Nvis of the star, (Arenou et al. 2018A&A...616A..17A), and the re-normalised unit weight error (RUWE), which measures how well the Gaia observations agree with the five-parameter single-star model and whose large value (RUWE>1.4) could indicate an astrometric binary (Lindegren 2018, Gaia technical note GAIA-C3-TN-LU-LL-124). We also added to Table 1 the stellar line-of-sight velocities, Vr, and their errors, e_Vr, taken from the catalog Barbier-Brossat and Figon (1999, Cat. III/213), which are available for 52% of stars of OB-associations.
