Top: histogram of all detections for Abell 85 in the range 22<i'<22.5 with the distributions of stars and galaxies obtained using our star-galaxy separation. Bottom: comparison of star counts obtained with the Besançon model (Robin et al. 2003) ( orange shaded region) and from the Abell 85 image ( black histogram) using our star-galaxy separation.

$\begin{figure} \par\includegraphics[width=9cm,clip]{f4.eps} \end{figure}$ Figure 4: Large-scale distribution of SDSS-DR6 galaxies around Abell 85. Large blue and small red filled circles represent cluster members (within $1500 ~ \rm km ~ s^{-1}$ from the cluster mean velocity) and outliers, respectively. The huge dashed circle represents the virial radius. The small and large squares show the WFI and MegaCam fields, respectively. The region $-8\hbox{$.\!\!^\circ$ }7 < \delta < -8\hbox{$.\!\!^\circ$ }5$ was not covered by the SDSS. XMM-Newton log-spaced X-ray contours and fields are shown in orange (main cluster) and purple (filament, with contour levels 1.1, 4 and 11 times lower than the lowest one of the main cluster).

The symbols are the following: filled red circles for ellipticals, filled green triangles for intermediate type spirals, and blue squares for late type spirals. Large black circles show the galaxies belonging to the dynamically bound substructure.

The H $\alpha$ detections are shown as black stars. Galaxies with only photometric redshifts are shown as green, blue, and red points, for $z_{\rm p}<0.5$ , $0.15 < z_{\rm p} < 0.3$ , and $z_{\rm p}>0.3$ , respectively.

$\begin{figure} \par\includegraphics[width=8.7cm,clip]{f14.eps} \end{figure}$ Figure 14: Same as Fig. 4 for the 101 galaxies detected in the H $\alpha$ filter, plus the SDSS galaxy. The blue circles show our H $\alpha$ detections for galaxies with spectroscopic redshifts that place them in ( filled circles) or out ( open circles) of the cluster. Galaxies that we detect in H $\alpha$ without spectroscopic redshifts are shown as red open squares or green crosses, depending on whether they have photometric redshifts (always at z>0.2) or no photometric redshifts, respectively. The galaxies detected in H $\alpha$ by the SDSS are shown as large circles with plus sign signs (in particular ACO85J004127.86-092329.54, which we did not detect in H $\alpha$ ).

The red circle shows the position of the cluster center, black circles are Abell clusters and crosses are other clusters found in the SDSS. Clusters and groups were selected to have a redshift within $\pm$ 0.005 of that of the cluster, in a region of $8.5\times 8.5$ deg²( $32\times 32$ Mpc²). Abell 85 is not exactly at the center of the figure because there are no groups or clusters towards the West and North of the cluster.
