Abstract

A detailed statistical analysis was carried out for several quasars with multiple red-shifts systems. The most important results are (a) The statistical test of the reliability of az-system is very sensitive toz, the total number of absorption lines, the selected set of reference lines and the number of identified lines (b) The standard deviation σ from μ, the average number of randomz-systems per random spectra is larger than μ. Consequently, the reliability of any system depends predominately on σ and not on μ.
