AVERAGE COOL-CORE and NON-COOL CORE PROFILES
Average profiles for the cool-core (CC, blue curves, 6 objects) and non-cool core (NCC, red curves, 12 objects) cluster populations, obtained either from the average density and pressure profiles or from the median of the 18 systems in common between the two samples. The error bars on the median profiles were estimated using a randomized bootstrap technique (see Eckert et al. 2012a).
ROSAT/PSPC proton density profiles (for the pressure see Planck Collaboration V 2013)
Average temperature profiles obtained from the median of the 6 CC (blue) and 12 NCC objects (red) and from the average Planck and ROSAT CC and NCC profiles
Average entropy profile obtained from the median of the 6 CC (blue) and 12 NCC objects (red) and from the average Planck and ROSAT CC and NCC profiles, and compared to the self-similar expectation (dashed line)
Average hydrostatic gas fraction profile obtained from the median of the 6 CC (blue) and 12 NCC objects (red) and from the average Planck and ROSAT CC and NCC profiles. The dashed line shows the WMAP7 universal baryon fraction
