We have re-analysed all available high-resolution ultraviolet IUE spectra of the high-mass X-ray binary HD153919/4U1700-37 .
The radial velocity semi-amplitude of 20.6 \pm 1.0 km s ^ { -1 } and orbital eccentricity of 0.22 \pm 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 ( [ ] ) and by Stickland & Lloyd ( [ ] ) .
