Description:
    Gunn g, r, i photometry for the 7 clusters MRC0254-274, Cl0317+15,
    MS0418.3-3 844, Cl1141-283, A1689, A3594, S0781B is presented. For
    each cluster we derived the spatial distribution properties obtaining
    the core radius and the concentration parameters. Color properties of
    the cluster galaxy population are also briefly discussed.
