Projected (left) and deprojected (right) t_cool/t_ff profiles for our evaluation sample. Dotted lines on both panels show the equivalent parameters if the isothermal mass component associated with the BCG is neglected. Horizontal error bars in the left panel reflect bin width. The same bin widths are used in the right panel but are not shown. Minimum values of t_cool/t_ff lie in the range 14.8–21.8 for our deprojected profiles.
