Notes. The first column (“Sample”) lists the reference paper for the parent sample: (B25) for the color-selected sample, (D23) for the Dn4000-selected sample. The second column (M⋆) indicates the stellar mass range of the subsample. Columns 3 to 6 only apply to the Dn4000-selected sample: the third column (“IR”) marks whether the galaxies in the sample have a detected Herschel counterpart and can thus be considered dusty, the fourth column (“Dn4000”) indicates the Dn4000 bin (in this case, ∀ means Dn4000 > 1.5, as it is one of the selection criteria for quiescence). The fifth column (“δ”) indicates the overdensity value used as an environmental flag, and the sixth column (“Morph”) marks the morphology class. The seventh column (“Ngal”) indicates the number of galaxies composing the subsample, while the last two indicate the estimated HI mass after a 10% confusion correction (Sinigaglia et al. 2022; Bianchetti et al. 2025), equipped with its uncertainty (“MHI”) and signal-to-noise ratio (“SNR”). If the HI mass estimate comes with the symbol *, then it refers to an upper limit at SNR = 3. The ∀ symbol means that there is no selection for that particular value.
