Notes. An additional error of about 0.07 magnitudes has been added in quadrature to the K-band magnitude errors: this is the scatter in the transformation of 2MASS reference star magnitudes from Ks to K, using Ks = K + 0.002 + 0.026(J − K). Magnitudes are not corrected for Galactic extinction (see Fig. 4). ( † ) Photometry from Chrimes et al. (2022b).
