Table B.1.

ALMA rest-frame 260 μm (observed-frame 870 μm) flux densities (F), effective radii (Re), and ratio between major and minor axes obtained with two methods: 1) fit on the image (created with natural weighting) and 2) using uvmodelfit. For both methods we assume a 2D Gaussian profile. For the two point sources (cid_1057 and cid_1205), the sizes are not reported. () If the peak S/N < 8 in the ALMA maps, we do not consider the size measurements to be reliable.
