Spectra of six known brown dwarfs obtained from NIRISS WFSS (dark blue), in comparison with the previously published spectra obtained with Subaru/MOIRCS (dark orange) from A. Scholz et al. (2009, 2012a, 2012b). NIRISS spectra were normalized to the average flux between 1.39 and 1.41 μm. MOIRCS spectra were scaled to match the NIRISS F150W spectra—an offset between the NIRISS F200W data and the MOIRCS data is evident, but not consistent between objects. See Section 3.4 for further discussion.
