NGC 1068 and the advantage for the image restoration of combining low frequency AT data with UT data. Left image: u–v coverage, with the AT baselines as blue dots, and the UT baselines are represented as red dots. Two left images: reconstructions are with UT baselines only, while the two right ones combine the baselines of UTs and ATs. The IRBis images are grey reconstructions over the 3.4–4.0 μm interval. The MIRA images are medians of all the 0.1 μm obtained between 3.4 and 4.0 μm.
