STATISTICAL PROPERTIES OF THE LEDA REDSHIFT DATABASE

We present the statistical properties of large scale galaxy distributi on in the LEDA redshift database. This catalog contains more than 40,0 00 redshifts over all the sky We find that LEDA, although seriously af fected by incompleteness, shows quite stable statistical properties. I n particular, we have considered the behavior of the two points correl ation function and of the power spectrum of the density fluctuations, and we have done several tests to check whether the incompleteness of the catalog affect these statistical quantities. Our conclusion is tha t galaxy distribution in this catalog has fractal properties up to the distance similar to 200h(-1)Mpc with D = 2.1+/-0.2, with no sign towa rds homogeneity: this result is statistically stable. Finally, we comp are these results with those obtained in other redshift surveys, findi ng that this sample well reproduces the properties of galaxy distribut ion found in the different catalogs.
