Notes. The notations used are the same as in Table 2 (see table notes there). Due to the low S/N of the C IV spectra extracted from these two regions, the column density results of C IV absorbers are treated as upper limits with z and b fixed to the fitted H I values, correspondingly. The exception is the column density of absorber #1 in the NE, which has a well distributed probability (see Fig. G.1).
