Description:
    We present spectrophotometry of a sample of 26 Southern binary
    galaxies. 17 pairs were confirmed to be physically associated with
    typical separation of 136h-1kpc. Pairs with velocity difference
    {DELTA}V≥600km/s are probably not physically bound. A comparison with
    field galaxies suggests that galaxies in pairs tend to have a younger
    population probably stimulated by tidal interaction. No correlation
    between the young population and projected separation was found. This
    table contains the quantities derived from the spectral data.

Note (1): Actually there is no quality parameter for n1741, since the spectra of
           this object is so rich in emission lines that the cross correlation
           technique could not be used.
