ATCA image at  ~7 mm of the Fomalhaut debris disk corrected for the attenuation of the primary beam pattern up to the half power point ( ≈ 33′′ from the pointing center). White contours are drawn at (–2, 2, 4, 6)  ×    σ, where 1σ ≈ 23 μJy is the rms noise level on the map. The orange star symbol identifies the location of the Fomalhaut star (α,δ) = (22:57:39.05, − 29:37:20.05), whereas the disk center is indicated by the blue cross, whose size corresponds to the angular resolution of the ATCA observations (≈2′′). Coordinates in the map have been corrected for the Fomalhaut proper motion (329/–164 mas yr^-1, from van Leeuven 2007), and are thus correct for the 2000.0 epoch. The red ellipse in the bottom left corner denotes the synthesized beam of the observations (FWHM ≈ 14.3 × 10.7′′, PA ≈  −76 deg).
