Scientific paper

The paper presents a nonparametric way of estimating distances to clusters of galaxies by using the Maximum Entropy Method. The data used to illustrate the method are angular positions and apparent diameters of galaxies, and a metric diameter-function deduced from a redshift survey in a small section of the sky. The reconstruction of the galaxy density as a function of the radial distance agrees with that deduced from redshift surveys. The method can be generalized for any distance indicator.
