Using the DR of SDSS we construct a sample of ٤٢٣٨٢ galaxies with redshifts in the region of 20 galaxy clusters reaching up to ٥ . Using two successive iterative methods the adaptive kernel method and the spherical infall model we obtained ٥٦ members belonging to the studied sample . We present the two - dimensional optical map for each cluster using the adaptive kernel method to determine their centers
