TeV surface brightness maps of HESS J1534−571, HESS J1614−518, and HESS J1912+101 in Galactic coordinates. The maps were calculated with a correlation radius of 0.1°. An additional Gaussian smoothing with σ = 0.01°was applied to remove artifacts. The surface brightness is expressed in units of counts above 1 TeV, assuming a power law with index Γ_ref. The inlets show the point spread function of the specific observations after applying the same correlation radius and smoothing, respectively. Top panel: HESS J1534−571, assumed Γ_ref = 2.3. The green ellipse denotes the outer boundary of the radio SNR G323.7−1.0 from Green et al. (2014). Contours are 3, 4, 5, 6 σ significance contours (correlation radius 0.1°). Middle panel: HESS J1614−518, assumed Γ_ref = 2.4. The green circle denotes the position and extent of 3FGL J1615.3−5146e from Acero et al. (2015). Contours are 5, 7, 9, 11 σ significance contours (correlation radius 0.1°). Bottom panel: HESS J1912−101, assumed Γ_ref = 2.7. Contours are 3, 4, 5, 6, 7 σ significance contours (correlation radius 0.1°).
