Binary template fits to three orders of the IGRINS spectrum of 2MJ1235AB using TWA 9B as the template for both the primary and secondary components. Each panel shows the spectrum of TWA 9B shifted to the wavelength of the primary and secondary components of 2MJ1235AB and adjusted to the flux ratio found by the fit. The panels also show the spectrum of 2MJ1235AB and the combined binary template after the duplicated spectra of TWA 9B have been shifted; fit for flux ratio, veiling, and continuum offset; and combined into a binary template. The results of fitting for flux ratio and veiling, which were measured independently of each order, are displayed on each of the panels above.
