Results of the spectroscopic survey for object NIRISS-NGC1333-6 (NN6). Panels shown are the same as in Figure 5. The calibrated slope image cutouts show that there is contamination from a nearby source (evident by a small trail in the upper right of both cutouts, overlapping the NN6 spectrum at longer wavelengths). This causes excess flux at ∼1.65 μm and ∼2.2 μm, and the deviation from the model template in the top panel.
