Top: differential VHE γ-ray energy spectrum of HESS J1646–458. The data are fit by a power law dN/dE = Φ0 × (E/1   TeV) − Γ. Arrows indicate the 95% upper limits for spectral bins which are compatible with a zero flux within 1σ. Also shown are spectra as obtained for region A and B. Bottom: residuals of the power-law fit for the 1.1°γ-ray emission region.
