Synthetic soft X-ray (0.3–2 KeV) emission maps of the simulated nebula around ζ Ophiuchi (unabsorbed) rotated to the direction of motion of ζ Ophiuchi in Fig. 1 and set to the same scale. Top: Z01 at an angle of 90° with respect to the direction of stellar motion. Middle: Z02 at an angle of 45°. Bottom: Z03 at an angle of 45°. Coordinates are in parsecs relative to the position of the star (white cross) and the colour scale is from zero to maximum in erg cm⁻² s⁻¹ arcsec⁻². The image normal direction is the z-axis of the simulation.
