Left panel: DSS–2 red optical image of J 1332–3308 with VLA radio contours at 4.8 GHz overlaid in blue (negative are grey), and 8.4 GHz (shown in red, negative are white). 4.8 GHz radio contours are ±0.075, 0.3, 1.2, 4.8 mJy b^-1, the resolution is 1.7′′ × 1.2′′, p.a. 13°, and the 1σ noise level is 0.020 mJy b^-1. The 8.4 GHz contours are ±0.08, 0.16, 0.32, 0.64, 1.28, 2.56 mJy b^-1, the resolution is 2.7′′ × 1.8′′, p.a. 44°, and the 1σ noise level is 0.025 mJy b^-1. Central panel: DSS–2 red optical image of J 1332–3308 with VLA radio contours at 8.4 GHz overlaid in red (same as left panel), and 1.4 GHz (shown in black). The 1.4 GHz contours start at ±0.39 mJy b^-1 (3σ) and are spaced by a factor of 2, the resolution is 4.2′′ × 3.7′′, p.a. 61°. Right panel: DSS–2 red optical image of J 1332–3308 with ATCA radio contours at 2.3 GHz overlaid (shown in magenta) and 1.4 GHz VLA contours in black (same as central panel). The 2.3 GHz contours are ± 3σ = 0.45 mJy b^-1 (3σ) and are spaced by a factor of 2, the resolution is 9.4′′ × 6.2′′, pa 2°. In each panel the restoring beams are reported in the bottom left corner.
