Notes. The J = 2000 coordinates and distances are based on the Gaia DR2 catalog (Gaia Collaboration 2018). The DR2 distances have uncertainties of ≈0.7–1.2 pc. Spectral types, Teff and Log(L*) for CI, DL, DN, IQ Tau and UZ Tau E are adopted from Long et al. (2018). For CY, DG, and DM Tau, the distance-corrected values are taken from Luhman et al. (2010) and Herczeg & Hillenbrand (2014). The dynamical stellar masses for CI, CY, DL, DM and IQ Tau were taken from Simon et al. (2019). The stellar masses for DN Tau and the UZ Tau E binary stars were taken from Long et al. (2022). The stellar mass of DG Tau is taken from Gangi et al. (2022) (no uncertainties provided). The mass accretion rates, except for DM Tau, are from Gangi et al. (2022). The mass accretion rate for DM Tau is taken from Ricci et al. (2010).(*) Denotes the bynary systems.
