Table 2: Fractional entropy and pressure scatter obtained using the surface brightness peak (SB peak) and the center of large scale X-ray isophotes (SB center) as center of symmetry.
Region a Center Entropy Pressure
r<0.1 r500 SB peak $(0.179 \pm 0.011)$ $(0.629 \pm 0.011)$
  SB center $(0.193 \pm 0.008)$ $(0.667 \pm 0.012)$
r<0.2 r500 SB peak $(0.180 \pm 0.006)$ $(0.413 \pm 0.006)$
  SB center $(0.161 \pm 0.005)$ $(0.448 \pm 0.007)$
r<0.5 r500 SB peak $(0.227 \pm 0.010)$ $(0.276 \pm 0.009)$
  SB center $(0.233 \pm 0.012)$ $(0.272 \pm 0.007)$
a Circular region inside which the scatter is calculated. The radius is expressed in fraction of r500: radius inside which the cluster mass density is 500 times the critical density of the universe.
