These tables give the empirically determined reliability of the 2MASS 6x extended source "truth tables" in 0.5 mag bins of fiducial Ks=20 mag arcsec-2 elliptical isophotal Ks-band magnitude (k_m_k20fe). The tables are grouped into three e_score/g_score (E/G) ranges, and within each group there are tables corresponding to three different ranges of foreground stellar density.
