Fig. 7

image

Top: radial profile of the surface density of Chandra sources in the spatially complete sample that have a VISTA match with J< 18 in different rings around the optical cluster center. The horizontal blue line and the parallel dashed lines show the mean value and the uncertainty of the source density outside the 7 arcmin region. Bottom: radial profile of the surface density of all VISTA source with J< 18 in different rings around the optical cluster center. The horizontal line and the parallel dashed lines show the mean value and the uncertainty of the source density in several comparison fields.

This figure is made of several images, please see below:
