Best-matching velocity maps from the TNG300 simulated clusters obtained with the Siamese CNN analysis for the XMM-Newton observations. The zoom-in panel shows the XMM-Newton data for a region centered on the physical origin (0, 0 kpc) of the simulated cluster. All simulated maps are presented at a fixed physical scale to maintain consistency across the sample. The apparent difference in coverage between the panels (e.g., A3266 vs. Virgo) is a result of the different angular sizes and distances of the observed clusters. Showing the full simulated extent provides crucial context for the large-scale dynamics and merger history that drive the observed core kinematics, offering insights into the broader physical environment of the matched systems. These figures illustrate kinematic similarity based on the CNN-learned metric, rather than pixel-wise visual resemblance.
