Notes. Uncertainties in parentheses are given in units of the last digit. They take into account the error on Sν given by the Gaussian fitting procedure and the uncertainty on the free-free correction factor. Results obtained from maps belonging to the frequency range covered by setup 3 are highlighted in gray.

(a)

Peak flux density derived from the 2D-Gaussian fit to the continuum map, corrected for the primary beam attenuation and for the free-free contamination.

(b)

Peak flux density measured on the SMA map obtained at 343 GHz and smoothed to the resolution of the ALMA map.
