372 The debate on galaxy space distribution: an overview


Figure 13.1.ξ(r)measure in various VL galaxy samples. The general trend is an increase
of theξ(r)amplitude for brighter and deeper samples. In theinsert panelwe show
the dependence ofcorrelation length r 0 onsample size Rsfor all samples. The linear
behaviour is a consequence of the fractal nature of galaxy distribution in these samples.


1.17–2.1, which demonstrates the deviation ofξ(s)from thecanonical power-law
shape [6, 15, 21, 22].


13.8 (r)analysis


According to our criticism of the standard analysis, we have measured the
galaxy conditional average density(r)in all the three-dimensional catalogues
