The VLT-FLAMES survey of massive stars: atmospheric parameters and rotational velocity distributions for B-type stars in the Magellanic Clouds.

Atmospheric parameters, stellar masses, and rotational velocities have been estimated for approximately 250 early B-type stars in the Large (LMC) and Small (SMC) Magellanic Clouds from high-resolution VLT-FLAMES data using the non-LTE TLUSTY model atmosphere code. This data set has been supplemented with our previous analyses of some 50 O-type stars (Mokiem et al., 2006A&A...456.1131M, 2007A&A...465.1003M) and 100 narrow-lined early B-type stars (Hunter et al., 2006, Cat. J/A+A/466/277, Trundle et al., 2007, Cat. J/A+A/471/625) from the same survey, providing a sample of ∼400 early-type objects. Description: As part of a European Southern Observatory (ESO) Large Programme on the Very Large Telescope (VLT, Paranal, Chile) observations were obtained for over 700 stars using the Fibre Large Array Multi-Element Spectrograph (FLAMES), with the majority of these objects being O- or early B-type stars. Observations were taken towards three Galactic clusters, NGC 6611, NGC 3293 and NGC 4755; two LMC clusters, N 11 and NGC 2004 and two SMC clusters, NGC 346 and NGC 330. Details of the observational fields, target selection and data reduction were discussed in Paper I and Paper II, Evans et al., Cat. J/A+A/437/467 and Cat. J/A+A/456/623.

Note (1): Radial distances of the objects in the NGC 346 FLAMES sample with respect to the centre of star formation taken as the position of object 435 from the Massey et al. (1989, Cat. J/AJ/98/1305) catalogue of OB stars in NGC 346; RA=00:59:04.49, DE=-72:10:24.7. The centre of NGC 346 adopted in Paper II (Evans et al., Cat. J/A+A/456/623) for calculation of radial distances was obtained from the SIMBAD database (operated at the CDS, Strasbourg, France) and is actually the centre of the ionised shell of gas, which is offset from the cluster centre.

Note (1): Where it was possible to measure the projected rotational velocity of the secondary object in a double lined spectroscopic binary system, a second entry is given with "B" appended to the object identifier. Note (2): We do not give atmospheric parameters for those objects listed as Be stars (Be), double lined spectroscopic binaries (SB2) or classified with an uncertain spectral type (SP?). Note (3): Values marked with colons indicate parameters where fitting has been difficult and the uncertainties may be larger than normal. Note (4): Method as follows: M06 = values directly obtained from Mokiem et al. (2006A&A...456.1131M, 2007A&A...465.1003M) T06 = values directly obtained from Trundle et al. (2007, Cat. J/A+A/471/625) H06 = values directly obtained from Hunter et al. (2007, Cat. J/A+A/466/277) He = indicates the methodology outlined in Sect. 3.2 has been used to derived the atmospheric parameters. A = the temperature has been assumed based on spectral type
