Scientific paper

For 23 UV-continuum galaxies showing double-nucleus structure, the radial-velocity difference and linear separation of the nuclei, orbital mass M luminosity L, and M/L ratio are tabulated. The mean biased M/L for the double-nucleus galaxies is 3.8 + or - 1.6, a value typical of late-type galaxies rich in gas and young stars, and consistent with the M/L and the double-nucleus separation probably results from the nuclei being surrounded by the optical background of the parent galaxy.
