Notes. The extinction Av, stellar effective temperature (T_eff), stellar luminosity (log(L/L_⊙), mass, age, EW(Hα), and logṀ_ac columns are the results determined in this work. The ‘Type’ column refers to the Class (II or III) of the YSOs. The ‘Class’ column indicates if a YSO is a WTTS or a CTTS. The RA and Decl. are from ZTF. The complete table is available in electronic form at the CDS.
