\caption{Characteristic temperatures and cooling times. $T_{\rm h}$ is the
temperature outside the cooling region, $T_{\rm c}$ the temperature in the
center of the cluster as determined from a single temperature fit;
$r_{\rm c}$ is the characteristic radius of the temperature profile
(see Eq.~(\ref{eqn:tfit});
$r_{{\rm cool}}$ is the cooling radius for a cooling time of 15~Gyr
and $a$ is the power law index of the scaling of $r_{{\rm cool}}$ with
cooling time (see text for details). }
