Abstract (from CDS):

We have re-analysed all available high-resolution ultraviolet IUE spectra of the high-mass X-ray binary HD 153919/4U 1700-37. The radial velocity semi-amplitude of 20.6±1.0km/s and orbital eccentricity of 0.22±0.04 agree very well with the values obtained earlier from optical spectra. They disagree with earlier conclusions for the same data reduced by Heap & Corcoran (1992ApJ...387..340H) and by Stickland & Lloyd (1993MNRAS.264..935S).
