NOTE. Source name in boldface indicates that the source is resolved at 3.3 mm with the ATCA, see Sect. 3.2. a Continuum flux and position are from fits in the (u, v) plane. For sources that were detected at 3$\sigma$, both the point-source flux (P) and the integrated flux for a Gaussian (G) are shown. For sources that were not detected, the coordinates of the phase centre are quoted. b Calculated from the cleaned image. c Restored beam, using natural weighting. d Quoted value is 3$\sigma$ upper limit. e Large, elongated beam due to short integration time and availability of only three antennas with 3-mm receivers.
