Notes. The RA, Dec, G magnitude, effective temperature (Teff), parallax (Plx), and mass (M) are taken from Gaia EDR3 catalog (Gentile Fusillo et al. 2021). The spectral type (SpT), if it is known, is taken from SIMBAD. W1 and W2 magnitudes, as well as their uncertainties (unW1 and unW2) are taken from CatWISE. The calculated W1 and W2 model values (W1Mod and W2Mod) are also represented in the table. Magnitude $(\bar{χ} (W i))$ $\[(\bar{\chi}(\mathrm{W} i))\]$ and color (∑_W12) excesses values are shown. Final excess is the assessment of the infrared excess based on the methods used in this work. OnlyMag and OnlyColor mean the infrared excess is identified from the W1 and W2 magnitude excesses or the (W1–W2) color excess, respectively. Color+Mag means the infrared excess has been identified with both methods. Contaminated refers to sources rejected due to visual contamination in WISEView images. We show, for reference, the first 20 lines of 9893 in total.
