Smoothed X-ray count rate maps in the [0.5–1] keV band for DG Tau in logarithmic scale and with a pixel size of 0.25^″. Left: 2010 data set resampled using the EDSER technique, as explained in Appendix A. We marked the position of the star with a cross and the SW jet with a box. Right: Synthetic image of the base of the jet as derived from model HJ3 at t = 70 yr (see lower right panel in Fig. 7), rebinned to match the same pixel size and convolved with the specific PSF. The modelled region is marked with a box corresponding to the SW jet. The angular size of each panel is ≈14^″×14^″ (a different scale to that used in Fig. 11). In each panel north is up and east is left. Gaussian smoothing was applied on the images with kernel of width 0.5^″.
