Notes. (a) Central observed frequency of the CO(2–1) spectral window. (b)FWHM and position angle of the synthesized beam using Briggs weighting with a robustness parameter of 0.5. (c) 1σ line/continuum sensitivities after combining the two scheduling blocks for each object. For the line sensitivity, we use the 7.8 MHz (~10 km s−1) channels of the final data cube. (d)Flux estimated using the Butler-JPL-Horizons 2012 models and ephemeris information (see ALMA Memo #594).
