Fig. A.1


TeV surface brightness profiles of HESS J1534−571, HESS J1614−518, and HESS J1912+101. Left column: radial profiles; right column: azimuthal profiles, respectively. The shell models and Gaussian models (shown in the left panels) are from fits to the data. The point source simulation shown in the left panels is derived from the sum of three Gaussians fitted to a simulated point source as it would appear in the actual data set (cf. Sect. 2.3.1), arbitrarily normalized for good visual representation. The value of Θ in the azimuthal profiles represents the angle with respect to the Galactic latitude. The first wedge is at Θ = 0 ° , following wedges are added counter-clockwise. The angle with respect to north in equatorial coordinates is represented by Θ′.
