Scientific paper

In this paper we present spectral and photometric analysis of three X-ray selected clusters. Redshifts have been obtained for a limited number of galaxies for each cluster. Photometry in the three Gunn filters g,r,i is presented: objects have been automatically classified as stars or galaxies, and background (or foreground) galaxies have been recognized on the basis of the color-color diagram. Best fit parameters of a Schechter luminosity function have been derived in two cases. The cluster morphological compositions, based on galaxy colors, are discussed as a function of distance and X-ray properties. Evidence for morphology and luminosity segregation is discussed.
