  This work is a continuation of a previous publication {Thieberger and
Spiegel,astro-ph/0204485} concerning the use of two dimensional catalogues in
unraveling the large scale distribution of galaxies. Since the data in
two-dimensional catalogues are more plentiful than those in three dimensions,
the luminosity method can be helpful in using two dimensional data to unravel
the nature of the three dimensional distribution. In this work we analyse the
Cfa catalogue and demonstrate that the results indicate a distribution of two
dimensions in the nearer range and three dimensions in the farther range. The
possibility of a different regime for very short distances is discussed.
