Panel a: stellar masses estimated with the spectroscopic method (horizontal axis; Alcalá et al. 2014, 2017) and with the dynamical information traced by the ¹³CO emission from this work (vertical axis). Filled and open symbols present the disks with the integrated ¹³CO fluxes above and below 400 mJy km s⁻¹, respectively.Black, green, and red dashed lines denote the regions where the differences in mass are 0%, 25%, and 50%, respectively. Panel b: stellar masses estimated with the dynamical information from this work (vertical axis) compared with measured integrated ¹³CO fluxes (horizontal axis). Panel c: as in panel a but with a subsample of lowest ¹³CO flux density discarded. Panel d: as in panel b but the horizontal axis presents ¹³CO flux density. A vertical dashed line in (panel d) denotes our selection criterion for the subsample shown in panel c.
