Introduction

The OU-LE3 RICH-CL PF shall provide the refined estimate of the richness of the cluster candidates, as well as, for any galaxy of the galaxy photometric catalog, a membership probability of belonging to any of the cluster candidates.

The four input files are the Galaxies catalog (not mentioned on the figure above), the photometric redshift catalog, the photometric mask, and the catalog of cluster candidates.

The first output consists in a refined estimate of the richness, for each of cluster candidate. Several definitions of the richness might be possible. It is currently considered as an independant output, but it mght as well be merged as some additional columns into the input catalog of cluster candidates (see R-LE3-PRD-F-212 from RSD)

The second output is a table of membership probabilites of belonging to any cluster candidate, for each galaxy.
