X-ray characteristics of new EPCC clusters within  [0.15−1.0]  × r₅₀₀. Left: contours of iso-flux in the XMM-Newton [0.5−2]-keV band plotted in the (z,T) plane. Right: X-ray flux distribution of new high-redshift (z ∈  [0.8−1] ) clusters for σ₈ = 0.75 (blue), σ₈ = 0.80 (green) and σ₈ = 0.85 (red). The solid lines correspond to results obtained using the Jenkins et al. (2001) mass function while the dashed line was obtained using the Tinker et al. (2008) mass function.
