Results of the spectroscopic survey for object NIRISS-NGC1333-10B (NN10B)—the companion object of the binary NN10 (with NN10A shown in Figure 14). Panels shown are the same as in Figure 5. Similarly to NN10A (Figure 14), there is contamination in the F200W spectrum from a source that overlaps with the spectral trail—the data in this region is unusable and was removed (evident by the gap in the spectrum in the top panel between ∼1.95 and 2.1 μm). The cutouts also display a large white region (where all values are NaNs) to remove the spectrum of the primary object.
