Projected temperature distribution of an example case provided by the Galaxy Cluster Merger Catalog (ZuHone et al. 2016, 2018). Time epochs after 1.4 Gyr and 2.3 Gyr of collision initiation are shown. The initial parameter of the mass ratio is set to 3:1. The initial impact parameter is set at 1000 kpc in the z-axis direction, and the two clusters approach each other by moving along the x-axis. The locations of the BCGs in the subcluster and main cluster are indicated by blue and red crosses, respectively. Detailed results are shown in Fig. C.1.
