Radio map of the HESS J1303−631 region at 5.5 GHz overlaid with contours of the X-ray PWN (red) as detected with XMM-Newton (Abramowski et al. 2012). X-ray contours show the peak of the emission close to the pulsar with a trail expanding in the eastern direction. The blue circle indicates the position of the pulsar PSR J1301−6305. The black box determines the region used for the flux density upper limit calculation. New point-like sources are indicated with index numbers. The synthesised beam is determined by an ellipse with the major and minor axes of 3.79′′ and 3.65′′, respectively, and the positional angle of − 7.6°.
