| Object | log M*/M⊙ | log MHI/M⊙ | log MH2/M⊙ | SFR/M⊙ yr−1 | Tcon/Gyr |
|---|---|---|---|---|---|
| HCG 16a | 11.05 | 9.15 | 10.05 | 4.6 | 3.5 |
| HCG 16b | 10.84 | 8.70 | 9.17 | 0.46 | 5.6 |
| HCG 16c | 10.86 | 9.57 | 9.78 | 14.0 | 0.9 |
| HCG 16d | 10.61 | 9.73 | 10.01 | 16.7 | 1.2 |
Notes. Columns: (1) object name, (2) logarithm of stellar mass estimated from IR photometry (Lenkić et al. 2016), (3) logarithm of H I mass, (4) logarithm of the molecular hydrogen mass estimated from the CO observations compiled in Martinez-Badenes et al. (2012), (5) star formation rate estimated from the combination of UV and IR fluxes (Lenkić et al. 2016), and (6) the gas consumption timescale taken to be 1.3(MHI + MH2)/SFR.
