J−H vs. H−K diagram plotted as a two-dimensional stellar-density histogram using a binning of 0.01×0.01 and a seven-level color-coded scale such that high source densities (56 per bin) are dark green and the lowest densities (one per bin) are blue. The symbols are the same as in Fig. 5. The black solid line shows the MS locus (Kenyon & Hartmann 1995).
