(1) rms estimated for r < 60'' in the map; (2) mean brightness and uncertainty of mean computed by averaging intensities over an effective disk of radius 60 AU; (3) the flux density upper limit is computed also over the same effective area (radius = 60 AU). (*): background sources in map (see Table 2); (**): possibly a large debris disk (see Fig. 1 and Sect. 4.1.3).
