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.
