Notes. Individual columns list the source position, source and lens redshift (z_S, z_L), sky-plane (lensed) FIR and CO(1–0) luminosities, CO(1–0) FWHM and FIR continuum magnification. L_FIR is inferred from modified black-body fits integrated over 8−1000 μm. For completeness, we also include SDP.81 from Paper II (Rybak et al. 2023).

– derived from the CO(3–2) lines from our NOEMA observations.

– For G09v1.40 and G12v2.43, z_L are unknown.

– Derived from CO(2–1), assuming CO is thermalised.

– No lens model available.

– derived from ALMA observations, Project ID #2023.1.00432.S (PI: M. Rybak).

– Mean magnification for ALMA Bands 6, 7, and 8 continuum (Giulietti et al. 2023).
