Fig. 7.


Colour composite image obtained with the WFC/INT of the SZ source PSZ1 G097.52−14.92. The central dominant galaxy presents a magnitude r′< 13 and extends (up to surface brightness isophote μr = 25.5 mag arcsec−2) more than 2′ (∼100 kpc at the redshift of the cluster) from its centre. The circle encloses a 3′ radius region, where the majority of likely cluster members, showing r′> 15 mag are placed. The square marks the Planck SZ peak.
