Fig. 2.


JH + HK density plot for the FGK dwarf sample described in the text. The intensity scale is logarithmic. The colored lines show the location of the Brott & Hauschildt (2005) dwarf models for four different sets of 2MASS ZPs assuming solar metallicity and for the ZPs in this work assuming log Z = −0.5 in solar units. The colored stars mark the location of the models with Teff = 8, 7, 6, and 5 kK (from left to right), respectively. The large ellipse shows the 68.5% contour for a distribution assuming σJ = σH = σK = 0.0015 mag and the small ellipse the equivalent for the ZP uncertainties in this work. The straight yellow line shows the displacement that corresponds to an extinction with A1 = 0.1 mag and = 2.0.
