Upper panel: the X-ray luminosity within the cooling radius at which the cooling time equals 7.7 Gyr, LX,rcool (left), and that within the core radius of 4.8% R500, LX,core (right), vs. temperature. Lower panel: the total X-ray luminosity vs. temperature (left) and the total X-ray luminosity minus LX,rcool vs temperature (right). Shown are the three categories − strong cool-core (SCC), weak cool-core (WCC) and non-cool-core (NCC) clusters. The symbol representation is the same as in Fig. 1.
