^a The average stacked flux densities are computed with equal weights to avoid biases. Their approximate rms are computed as the standard deviation of the mean.
^b S/N at 1.2 mm.
^c $L_{\rm {FIR,mm}}$ is computed with (Eq. (3)) and the dust temperatures coming from the stacked SED (see text): 37 K for the entire sample, 36 K for the 13 sources with S/N > 3 at 1.2 mm, and 39 K for the 20 sources with S/N < 3.
