VizieR Online Data Catalog: VFTS. B-type stars classification and RV (Evans+, 2015)

All of the VFTS data discussed here were obtained using the Medusa-Giraffe mode of the Fibre Large Array Multi-Element Spectrograph (FLAMES) instrument on the Very Large Telescope (VLT). The Medusa fibres (which subtend 1.2" on the sky) were used to relay light from up to 130 targets simultaneously to the Giraffe spectrograph (see Pasquini et al., 2002Msngr.110....1P).

Full details of the observational strategy and reduction of the data are given in Paper I (Evans et al., 2011A&A...530A.108E). In brief, the ESO Common Pipeline Library FLAMES recipes were used to undertake bias subtraction, fibre location, summed extractions of each object, division by a normalised flat-field, and wavelength calibration. Subsequent processing included correction of the spectra to the heliocentric frame, sky subtraction, and rejection of significant cosmic rays.
