\caption{\label{agntabla}Coordinates of the AGN and the cluster. The AGN is almost at 
 the centre of the cluster emission. We also show the count rate for the 
 two objects (normalized for the different apertures, see text for 
 details) and the luminosities, both in the [0.3$-$10~keV] band (bolometric 
 luminosity for the cluster is given in Table~\ref{cuadro}). The contribution 
 of the AGN is larger than the cluster luminosity. Both objects are at the
 same redshift of~0.52. An optical counterpart of the AGN is marked in~Fig.~\ref{Rgal}.}
