Notes. The first column gives IDs of the detected sources, the second one lists coordinates. The third, fourth, and fifth columns give apparent magnitudes in I, R, and V band, respectively. The sixth, seventh, and eighth columns provide signal-to-noise of the flux with respect to the background variation in a given band, as indicated by the lower script (see Sect. 2.2.4 for details). The ninth marks possible foreground or background stars (see Sect. 3.1 for definitions). The next five columns flag matches with other catalogs: Gaia (Gaia Collaboration 2023), WFI (Beccari et al. 2015), VISTA (Preibisch et al. 2014), HAWK-I (Preibisch et al. 2011a,b), Spitzer (Povich et al. 2011), and Chandra (Preibisch et al. 2011a; Townsley et al. 2011). The following indicates if the star has an NIR excess as defined by Zeidler et al. (2016). In the consecutive nine columns are given stellar parameters: spectral type, effective temperature, visual extinction, constant veiling at 7500 Å, bolometric luminosity, and stellar mass and stellar age estimated from PARSEC (Bressan et al. 2012) and Baraffe et al. (2015)/Siess et al. (2000) tracks, as indicated by the subscript. A full version of this table is available at CDS. The first few rows are shown as an example.
