Left: H.E.S.S. excess map as shown in Fig. 1 but for an enlarged region of 4.5°  ×  4.5°. The blue-grey boxes denote the regions used to generate the one-dimensional slices shown on the right. The white circles denote regions A and B which were used for spectral reconstruction (Table 2). The weak γ-ray emission seen in the lower right corner next to HESS J1640–465 is HESS J1634–472, also detected during the GPS (Aharonian et al. 2006c). Right, top: distribution of VHE γ-ray excess events in the blue-grey box, oriented along the two emission regions associated to HESS J1646–458 and starting at low Declination angles. The results of a fit of a constant and of two sources with Gaussian shape are indicated as black and red line, respectively. Right, bottom: same as top, but oriented along the Galactic plane, starting at low Right Ascension angles, close to the bright source HESS J1640–465 at d =  −1.25°. The slice has been truncated at 350 excess events in order to emphasize the VHE γ-ray emission from HESS J1646–458.
