Temperature and metallicity profile of PLCKG287 compared to those of typical relaxed clusters. Left panel: temperature profiles measured for a sample of relaxed clusters presented by Vikhlinin et al. (2005). The temperatures are scaled to the cluster emission-weighted temperature excluding the central 70 kpc regions, ⟨kT_X⟩. The profiles for all clusters are projected and scaled in radial units of the virial radius R_vir, as estimated from the relation $R_{\mathrm{vir}}=2.74\mathrm{Mpc}\sqrt{⟨k{T}_{\mathrm{X}}⟩/10\mathrm{keV}}$ (Evrard et al. 1996). The values measured for PLCKG287 are ⟨kT_X⟩∼13 keV and R_vir ∼ 3.1 Mpc. The dotted cyan line indicates the region inside which there is a clear departure from the typical profile, with an opposite radial trend. We interpret this region as the former cool core; see text for details. Right panel: metallicity profile measured for PLCKG287 (red triangles) overlaid onto the metallicity profile observed for a sample of cool core clusters presented by De Grandi & Molendi (2001). The profiles for all clusters are projected and scaled in radial units of R_vir. H₀ = 50 km s⁻¹ Mpc⁻¹, Ω = 1, Λ = 0 is assumed for this plot and the virial radius was estimated from the relation $R_{\mathrm{vir}}=3.95\mathrm{Mpc}\sqrt{⟨k{T}_{\mathrm{X}}⟩/10\mathrm{keV}}$ (Evrard et al. 1996), resulting in ∼4.5 Mpc for PLCKG287.
