Figure 1: Absolute magnitude histogram of the galaxies in the five clusters. The dotted line shows the completeness magnitude limit for each cluster; the dashed line shows the common magnitude limit we have adopted for the five clusters. |

Figure 2: Left panels: the color-magnitude diagrams for the five clusters. The solid line is the fit to the red sequence and the dotted line is the upper 0.2 mag limit. The vertical line corresponds to the limit Mr = -20 at the cluster redshift. Right panels: the histograms of the B-r distance of the galaxies to the corresponding red sequence. |

Figure 4: Blue fraction of galaxies in our sample of clusters (triangles) compared with those obtained by De Propris et al. (2004) (black circles) for an aperture of r200/2. The top (bottom) panel corresponds to the blue fraction computed within a radius of 420 kpc (735 kpc). |

Figure 6: Cumulative functions of the different morphological types as a function of the projected radius to the center of the cluster. Early types: solid lines; late types: dotted lines. The vertical lines indicate the radius where the distributions reach the 50% level. |

Figure 7: Concentration parameter versus redshift for our clusters (triangles), a low-redshift compilation (Butcher & Oemler 1978: black points) and a higher redshift sample (Dressler et al. 1997: asteriks). The horizontal line is the mean concentration value of the clusters with enough area coverage. |
