The Relation between the Cool-core Radius and the Host Galaxy Clusters: Thermodynamic Properties and Cluster Mass
Temperature profile of the intracluster medium for our sample (RXCJ1504.1-0248, A3112, A4059, and A478) scaled by the cool-core radius and the peak temperature for the horizontal and the vertical axes, respectively.
The red dashed line and shaded region display the best-fit profile and 1σ uncertainty, respectively. The blue, vertical solid line indicates rcool = 1. The residuals and mean absolute relative residuals are shown in the middle and bottom rows, respectively.
