Analysis regions for emission-projection plots as shown in Fig. 8. Here, we show the corresponding circles overplotted over a projection for the synchrotron emission at 31.6 keV with an inclination of i = 60°. The small white circle indicates the region, for which we summed up the emission around the bow shock. The larger circle was used as an approximation for emission from the sheath around the pulsar, where the emission around the bow shock was subtracted.
