Comparison of the W2 vs. ch2 apparent magnitudes for objects within the 20 pc census that have measurements in both bands. Objects identified as low-gravity, low-metallicity, or having unresolved multiplicity are color-coded per the legend. Brown line shows the linear least-squares fit to the data, excluding color-coded objects. Parameters for this fit are given in Table 13.
