Weymann, R. J. ; Boroson, T. A. ; Peterson, B. M. ; Butcher, H. R. Abstract The fields of six QSOs with low absorption-line redshifts, z(a) no more than about 0.6, have been examined on deep photographs for possible intervening galaxy images. No images less than about 60 kpc distant from the line of sight to the QSO (on the intervening hypothesis) were found. It is shown that unless the correlation between absorbing clouds and galaxies is substantially stronger than the galaxy-galaxy correlation, 'field' galaxies will always be more numerous than 'correlated' galaxies for cases of interest. It is also concluded that for Stockton's sample of low emission redshift QSOs, the QSO-galaxy correlation is stronger than the galaxy-galaxy correlation.
