Component	log $M_{dyn}^{uncorr}$ $M_{\mathrm{dyn}}^{\mathrm{uncorr}}$	log M_dyn	log M_disp	log M_dust	log M_gas	log M_mol
	[M_⊙]	[M_⊙]	[M_⊙]	[M_⊙]	[M_⊙]	[M_⊙]
QSO host	10.9 ± 0.1	11.4 ± 0.1	10.5 ± 0.1	8.5 ± 0.4	10.5 ± 0.4	10.9 ± 0.3

Notes. Columns: (1) Component; (2) Uncorrected dynamical mass ( $M_{dyn}^{uncorr} = M_{dyn} \times {sin}^{2} (i)$ $M_{\mathrm{dyn}}^{\mathrm{uncorr}} = M_{\mathrm{dyn}} \times \sin^2(i)$ ); (3) Dynamical mass (M_dyn) estimated using Eq. (2); (4) Dispersion mass (M_disp) estimated using Eq. (3); (5) Dust mass (M_dust) estimated using Eq. (4); (6) Gas mass (M_gas) derived from M_dust and a GDR; (7) Molecular gas mass (M_mol) derived from [CII] using Eq. (5) from Zanella et al. (2018). All masses are reported in M_⊙.
