Left: uncorrolated excess images of the HESS J1303−631 region in the energy bands E₁ = (0.84−2) TeV, E₂ = (2−10) TeV and E₃ > 10 TeV (from top to bottom). Coordinates are J2000.0. All images were smoothed with a Gaussian kernel of width 0.05°. Slices are indicated by the rectangles, taken in the direction of the semi-major axis of the fitted asymmetric Gaussian function. Right: the slices on the uncorrelated excess images are then fitted with a Gaussian function. The pulsar position is marked by a green star in the sky maps and a dashed line in the profiles. The dashed curves show the energy-dependent PSF of the H.E.S.S. instrument.
