Correlation coefficient r for the z-distributions
of the C IV  absorption systems

Figure 3: Correlation coefficient r for the z-distributions of the C IV absorption systems in pairs of opposite hemispheres for Equatorial and Galactic coordinate systems: (a) dependence r on the right ascensions ac (bottom horizontal axis) and a'c (top horizontal axis) of the centers of two complementary hemispheres, (b) dependence r on the Galactic longitudes lc (bottom horizontal axis) and l'c (top horizontal axis) of the centers of two complementary hemispheres. The tabulated values rb=0.588 for the confidence level b=0.999 (>3s) and rb=0.375 for b=0.950 (2s) are represented.
