SSOF model of KO 137 for HD 26965 which can effectively model its portion of the spectrum with only a stellar template. Top: the flux outputs of the model—﹩{Y}_{\oplus }^{{\prime} }﹩ (blue) which has no telluric transmission (blue) and ﹩{Y}_{\star }^{{\prime} }﹩ (orange), a constant stellar model. Middle: the per-pixel mean absolute deviation (MAD) of Y_D − Y_M. The majority of the spectra is modeled to >99% accuracy. Bottom: the remaining χ² for each observed pixel. All parts of the spectra are modeled equally well in a χ²-sense. The residuals between v_⋆,137 and ﹩{v}_{\star }^{{\mathtt{SSOF}}}﹩ are shown in Figure 11.
