Top panel: radial profile within 3′′ from the source PSR (histogram in black) compared to the PSF (dashed red line) simulated with the ChaRT tool at the PSR position and with the measured energy spectrum. Bottom panel: same plot as above, but for the regions marked in the inset picture. Positive radial distances are in front of the source, in the SW direction, negative are backwards in the NE direction (i.e. in the direction of the PWN).
