Notes.

^(a)

Weight scheme associated to each candidate, as explained in Sect. 3.2.

^(b)

3-σ upper limits of weighted average for each bin (Eq. (16)).

^(c)

CLEANing method used in CASA to obtain final image.

^(d)

Maximum value from a box in the stacked images.

^(e)

rms errors from Eq. (6).

^(f)

S/N = Flux_peak/rms.

^(g)

Since IRX values are obtained from ALMA images and stacked fluxes from visibilities, we do not have coverage in the image but we are able to u–v stack that position.
