Notes. (1) Stellar mass range of the bin. (2) Number of CO-VGS galaxies in the bin. nup: Number of upper limits of CO-VGS galaxies in the bin. (3) Mean logarithm of the star formation efficiency and its error of the CO-VGS galaxies in the bin. (4) Median logarithm of the star formation efficiency of the CO-VGS galaxies in the bin. (5) – (7) The same for the CO-CS sample. (8) Difference of the mean logarithmic of the star formation efficiency between CO-VGS and CO-CS (Δmean) and its error (err(Δmean)). (9) σ = Δmean/err(Δmean). (10) p-value of the Kolmogorov-Smirnov test.
