(a) Chandra ACIS-S 0.3–8 keV X-ray image of NGC 1068 (in the same 40″ × 40″ central region of the MUSE maps from Figs. 6 and 7; reported values are photon counts). Contours of [O III] W70 (from Fig. 7b) are reported in white. (b) Top panel: spectrum (black points) extracted from the magenta region reported in panel a. The apec + pshock best-fit model is shown in red, and its separate components in other colours. The vertical dotted line marks 6.4 keV. The residuals of the apec + pshock and apec + apec fitting procedures (see text for further details), with Δ = (data − model)/error, are reported for comparison in the middle and bottom panels, respectively.
