Comparison of spectroscopically inferred T_eff, ﹩\mathrm{log}(g)﹩, f_sed, and R values between Sonora Diamondback and SM08 model grids. Uncertainties in T_eff, ﹩\mathrm{log}(g)﹩, and f_sed are adopted as half the model grid spacing and are not plotted for clarity. Model grids are indicated by gray dashed lines. In the ﹩\mathrm{log}(g)﹩ and f_sed panels, data points are clustered at discrete grid values; the number of targets at each value is labeled.
