Notes. Columns show the target name; 1 mm spectral index, α1mm; spectral index between the 3 mm and cm data, α3mm-cm; extrapolated spectral index between the 3 mm flux without the dust contribution and the cm data, αextrap; spectral index of the central emission, αinner; and the spectral index of the outer disk emission, αouter.(*) We report the confidence interval [αextrap, α3mm-cm] for the spectral index of the central emission, while the average value in the interval that we used to calculate the ionized mass loss rate is reported in brackets. See the text for further details.
