Notes. Columns are: source name; right ascension and declination; apparent major axis and minor axis FWHM, and position angle measured on the PdBI CO(4–3) map; intrinsic flux density at 850 μm; delensed FIR luminosity integrated in the range 8–1000 μm and star-formation rate given for a Chabrier IMF; intrinsic velocity-integrated flux and luminosity of CO(4–3) line; molecular gas mass assuming R4, 1 = 0.55 and αCO = 0.8 M/(K km s−1 pc2). Intrinsic quantities are corrected for the local magnification factors, μCo − N = 6.1 ± 0.9 and μCo − S = 3.8 ± 0.5, inferred in Sect. 4.3, and errors include statistical uncertainties on μ.
