Column density ratios (in log) between the other components and their corresponding Component 1: log N/Ncomp1 against distance. The column density is that of Fe II when available and Mg II otherwise. The dots are components 1. They show the position of all lines of sight. The other components, numbered in order of increasing | ΔV | relative to Component 1 are as follows: black squares are Components 2, red triangles Components 3, green diamonds Components 4 and blue crosses Components 5 and 6.
