A Detailed Far-UV Spectral Atlas of B Main Sequence Stars ("FUVBSTARS")

The Far-UV Spectral Atlas of B stars (Smith 2010) contains high resolution data in the far-UV wavelength region (defined here as the range 949-1225 Angstroms) for 10 B stars near the main sequence. The spectrum for type B0 is taken, with permission from the author, from the still classic Copernicus satellite atlas of tau Scorpii (Rogerson and Upson 1977). For all other types the spectra were obtained from the MAST/FUSE data archives (Far Ultraviolet Spectroscopic Explorer) in the range 949-1188 Angstroms, and from the archives of either the HST/STIS or IUE archives for wavelengths above 1188 Angstroms. Whenever both data sources were available the STIS spectrum was selected. With respect to the data in the MAST archives, the altas spectra are enhanced, first, in that wavelength irregularities for the FUSE Side 1 and Side 2 spectra have been removed to the greatest extent possible and corrections made for the stars' radial velocities. The spectra were then resampled to restore the wavelength zeropoints and increments of the original spectra. Second, the depressed fluxes in the FUSE 1B LiF detector segment due to the primary 'worm' have been corrected by means of the quasi-continuum fluxes in the 2A LiF segment. Third, a star/ISM flag vector was added to the FITS files to designate those wavelengths for which the fluxes are dominated by local molecular hydrogen lines.
