Maps of X-ray flux in the 0.5−7 keV band (top-left), spectroscopic-like temperature (top-right), EM-weighted l.o.s. velocity (bottom-left) and EM-weighted l.o.s. velocity dispersion (bottom-right), for z-axis projection (i.e., for the merger in the plane of the sky). The projection is performed over 10 Mpc along the l.o.s. (z-axis). Overplotted, the seven pointings of 200 kpc per side (roughly 3′ at the assumed redshift of z = 0.057) analyzed in Sect. 4.1.
