Appendix 5. Working Database Source Reliability Estimation

2. Extended Source Reliability Estimation

Tables 2-13 - Survey Scan Extended Source Reliability Matrices

These tables give the empirically determined reliability of the 2MASS Survey Scan extended source "truth tables" in 0.5 mag bins of the fiducial Ks=20 mag arcsec-2 elliptical isophotal J-band magnitude (j_m_k20fe). The tables are grouped into three e_score/g_score (E/G) ranges, and within each group there are tables corresponding to four different ranges of foreground stellar density.
