Mean specific star formation and R₅₂ ratio for our sample.

	sSFR	R₅₂
	(Gyr⁻¹)
All post-SBs	0.006	$0 . 28_{- 0.13}^{+ 0.15}$ $Mathematical equation: $ 0.28^{+0.15}_{-0.13} $$
Merging post-SBs	0.004	$0 . 40_{- 0.15}^{+ 0.15}$ $Mathematical equation: $ 0.40^{+0.15}_{-0.15} $$
Non merging post-SBs	0.007	< 0.10
Companions ID83492	10.716	0.12

Notes. The R₅₂ is estimated as an average in case of CO(5–4) detections, namely the merging post-SBs and the companions of ID83492. The uncertainty for the merging post-SBs is estimated through bootstrap, while we do not estimate an uncertainty for the companions as they are only two. For the CO(5–4) non-detections R₅₂ is estimated through stacking (Sect. 4.1). For the entire population we estimated the mean ratio using the Kaplan–Meier estimator from survival analysis to account for measurements and upper limits (Sect. 4.1, with uncertainties estimated through bootstrap. For ID83492 and ID97148 we estimated the CO(2–1) flux assuming R₃₂ = 0.62, while for their starbursting companions we adopted R₃₂ = 0.78 (Sect. 4.1).
