Smoothed X-ray count rate maps in the [0.3–4] keV band for HH 154 with a pixel size of 0.25^″. Left: 2005 data set resampled using the EDSER technique, as in Bonito et al. (2011). Right: Synthetic image of the base of the jet as derived from model LJ5 at t = 100 yr (see lower right panel in Fig. 2), rebinned to match the same pixel size and convolved with the proper PSF. The angular size of each panel is ≈7^″ × 7^″. In each panel north is up and east is left. Gaussian smoothing was applied on the images with kernel of width 0.5^″.
