Image of the VHE γ-ray excess centered on HESS J1356−645, smoothed with a Gaussian of width 0.13°. The linear colour scale is in units of excess counts per arcmin². The black contours correspond to the 5, 7 and 9σ levels for an integration radius of 0.22°. The black cross indicates the best fit position of the source centroid together with its statistical error. The intrinsic Gaussian source size is shown by the white dashed circle. The dotted circle indicates the region of spectral extraction (see Fig. 2). The position of PSR J1357−6429 is marked with a green triangle. The white solid circle represents the 68% containment radius of the resulting point spread function.
