FUSE Spectral Atlas of Wolf-Rayet Stars ("FUSE_WRATLAS")

The FUSE Wolf-Rayet Atlas is taken from the paper by Willis et al. 2004. This paper presents full FUSE wavelength coverage for 21 Wolf-Rayet stars distributed among WN and WC types and located in the Galaxy or either of the Magellanic Clouds. As in other FUSE MAST HLSP O-star atlases, the emphasis in the companion paper (see Willis et al. 2005) and in the figures included herein is in the presentation of data for many resonance lines from ions spanning a wide range of ionization potential. The data were obtained through the 30 X 30 arcsec (large) science aperture. The data have been processed beyond the pipeline stage to produce a single merged spectrum for each star. The post-processing steps include suppression of nightglow emission lines (by using only orbital-night data for these wavelengths), correction for the LiF1B channel 'worm' by using continuum information from the LiF1A channel, use of guiding channel fluxes and generated errors to assign relative weights to fluxes in wavelength regions where channel data overlap, and a binning of the data to 0.1 Angstroms (15 pixels). The resulting spectra have a signal to noise in the range of 20 to 50 per wavelength bin. The wavelength scales of the spectra are heliocentric. No attempt has been made to rectify the stellar continuum fluxes.
