X-IFU maps showing input quantities (top panels) vs. measured ones (bottom) for the ℳ = 0.75 model. Input quantities are derived directly from the simulation output, considering the average along the line of sight enclosed by the X-IFU pixel (4.38 arcsec wide) and computed with the definitions in Eqs. (3)–(6). For measured quantities we show the nominal value derived from the fitting of our synthetic spectra (see text for details) in the corresponding 588 Voronoi regions (≈125 arcsec² each). From left to right: emission measure, gas temperature (spectroscopic-like, in the top panel), velocity, and velocity dispersion (both emission-weighted, in the top panels).
