                    Caption: Figure 20.
Plots of various absolute magnitudes (a)–(c) and colors (d)–(e) as a function of JMKO − ch2 color. Only members of the 20 pc census are shown, and plots (a)–(c) show only the subset of 20 pc objects having parallaxes measured to better than 12.5%. All five panels are supplemented with W2 magnitudes when ch2 is not available, as described in Section 7.4. Polynomial fits that exclude known young objects (pink circles, Section 7.1), subdwarfs (blue squares, Section 7.2), and multiple systems (yellow diamonds, Section 7.3) are shown in brown and described in Table 13. These fits are restricted to points with MJMKO ≥ 16.0 mag in panel (a), MH ≥ 15.0 mag in panel (b), and Mch2 ≥ 13.0 mag in panel (c).
