Scientific paper

Low-resolution IUE ultraviolet spectrophotometry is presented of 15 galactic WR stars, covering most subtypes in the WN and WC sequences. The data are presented both as spectral plots and as tabulations of the observed absolute flux distributions covering the wavelength range of 1150-3090 A. The characteristics of these UV WR spectra are discussed, the equivalent widths of the most prominent emission lines having been measured. It is shown that the WR stars adhere to the normal galactic interstellar extinction law. For each star, color excesses, E(B-V), are derived by nulling the observed 2200 A features and by comparing relative intensities of optically thin HeII recombination emission lines.
