VLA1.4 GHz radio image of the radio nebula G10.0−0.3 (contour levels at −3, 2, 4, 6, 8, 10, 12, 14, 20, 25, 30 × 1.56 mJy/beam; black circle indicating an ASCA X-ray source location) from Kulkarni et al. (1994) with red solid VHE γ-ray contours of HESS J1808−204 (as per Fig. 1). The 68% location error of 3FGL J1809.2−2016c is indicated by the magenta dashed ellipse, and locations of SGR 1806−20 (x) and LBV1806−20 (+) are indicated.
