Notes. Values for metallicity and surface gravity are in dex. Uncertainties are not quoted, but formal errors for temperature are ±250 K, for surface gravity ±0.5 dex, and for abundances ±0.3 dex. Effective temperature, surface gravity, and abundances come from the literature, quoted in the last column. The E(B − V) values come from SED fitting (see Sect. 3.2), and the infrared luminosities are computed by integrating the infrared excess in SEDs in Appendix A.
