Notes. The columns of the table show the ID of each sample, the number of sources, their median stellar mass, star-formation rates, molecular gas mass, gas fraction, and global and local environmental parameters. Errors for each quantity are calculated using their standard deviations. The first three rows display the three stellar mass bins of our protocluster sample: HAEs with M < 1010.5 M; HAEs with M* > 1010.5 M; and AGN candidates with M* > 1010.5 M. The rows below the solid line display the protocluster comparison sample of Wang et al. (2018) (W18), and the field samples of Kaasinen et al. (2019) (K19), Riechers et al. (2020) (R20), and Frias Castillo et al. (2023) (FC23).

(a)

The molecular gas mass and its uncertainty were derived by stacking the CO(1−0) emission from the sources in these samples, rather than calculating the median and standard deviation of the distribution.
