Fig. 1


VHE γ-ray emission of RCW 86. The sky map is extracted with faint analysis cuts and smoothed with a Gaussian filter with σsmooth = 0. ° 06 to reduce the effect of statistical fluctuations. Black contours correspond to 3, 5, 7σ significance. The white dotted circle depicts the integration region chosen for the spectral analysis. The dashed cyan sector shows the position angle range of the radial profile in Fig. 3. The two green sectors (solid lines) give the extraction regions for spectra of the SW and NE regions discussed in Sect. 3.
