$\begin{figure} \par\includegraphics[width=8.4cm,clip]{0575fig1.eps}\end{figure}$ Figure 1: Summary of the X-ray observations of Mrk 205; evolution with time of the photon index $\Gamma$ , the hydrogen column density in the line of sight $N_{\rm H}$ (the dotted line denotes the Galactic value) and the 2-10 keV flux (units: 10^-11 erg cm^-2 s^-1). Data from Table 1. We have included as well an IUE light curve at 1300 Å (units: 10^-14 erg cm^-2 s^-1 Å^-1).

$\begin{figure} \par\includegraphics[width=15.3cm,clip]{0575fig2.eps}\end{figure}$ Figure 2: Left panel: MECS intensity image of the 2001 observation with contours at (from the outside) 7.7, 15.5, 23.3, 31.1, 38.8, 46.6, 54.4, 62.2 counts. Right panel: profile along the dotted line displayed on the left panel (1 MECS pixel is 7 $^{\prime \prime }$ ). NGC 4319 is located 6 pixels on the left of the central peak in a region which accounts for 54% of the peak value.

PDS data are included without being fitted but with an intercalibration constant frozen to 0.88. Lower panel: residuals with respect to the MECS best fit model.
