Fig. 1
Residual counts map above 2 GeV, derived by subtracting the best-fit model map from the counts map. The unit of the map is counts per pixel while the pixel size is 0.1° × 0.1°. Green contours show the HESS image of the SNR at 10, 30, 50, 70, 90% of the corresponding peak value of 134 counts per 0.04°×0.04°. The other nearby TeV source HESS J1729-345 is not shown here. The new point source with a TS value 20 mentioned in the text is not subtracted in this residual map.
