FUSE Atlas of Galactic OB Stars ("FUSE_GALOB")

The first of the two FUSE data catalogs contains an atlas of far-ultraviolet spectra of 45 OB (O2-B3) stars in the Galaxy (see Pellerin, Fullerton, Robert et al. 2002; ) for the spectral region 920-1180 Angstroms. All data were obtained through the 30×30 arcsec (large) science aperture. The original data resolution and reciprocal spectral dispersion were 15-20 km/s and 0.062-0.067 Angstroms/pixel, respectively. The data were further resampled to 0.12 Angstroms/pixel for this atlas. Most spectra were obtained in a series of back-to-back exposures. Tests indicated that apparent wavelength shifts among them are less than half a resolution element. The final spectra were constructed with simple coadditions.
