SMART fits to IGRINS spectra for W1741–46 (top) and 2M2206–42 (bottom). The grey line is the observed IGRINS spectra, the red line is the fitted model including telluric absorption, and the blue line is the fitted model without tellurics. At the bottom of each plot is the residual between the model (including tellurics) and the observed data. The shaded blue region is the ±1σ uncertainty.
