Notes. Column names and several lines are shown to demonstrate the data structure. [H97b] is the Simbad identifier of the data from Hillenbrand (1997) with multiplicity index. [HC2000] is the Simbad identifier of the data from Hillenbrand & Carpenter (2000). [MLLA] is the Simbad identifier of the data from Muench et al. (2002). [FDM2003] is the Simbad identifier of the data from Flaccomio et al. (2003a,b), where Opt is for the optical, X is for the X-ray, and X₂ is the identifier of an additional X-ray source that was also cross-matched to the optical data. [DRH2012] is the Simbad identifier of the data from Da Rio et al. (2012). [COUP] is the Simbad identifier of the data from Getman et al. (2005a). [PMF2008] is the Simbad identifier of the data from Prisinzano et al. (2008). M_H97b is the mass given in Hillenbrand (1997). M_FDM2003 is the mass given in Flaccomio et al. (2003a,b). M_B98 is the mass given in Da Rio et al. (2012) from Baraffe et al. (1998). M_DM98 is the mass given in Da Rio et al. (2012) from D’Antona & Mazzitelli (1998). The complete dataset is available at the CDS.
