Left: exposure-corrected excess map for RX J0852.0−4622. The data were binned in bins of 0.01° on each coordinate and smoothed with a Gaussian function of width 0.08°. The white dashed line shows the position of the Galactic plane; the inset shows the PSF of the analysis at the same scale for comparison. Right: same as in the left panel, but additionally the boundary of the ON region is shown as a white circle and the significance contours at 3, 5, 7, 9, and 11σ are shown in black with increasing line width for increasing significance. In addition, X-ray contours from the ROSAT All Sky Survey for energies larger than 1.3 keV are shown in red. The X-ray data were smoothed in the same way as the γ-ray data to allow for a direct comparison. The X-ray contours were derived at 25, 50, 75, and 100 counts. The green star indicates theposition of PSR J0855−4644.
