Caption: Figure 14. Peculiar spectra

The complete figure set (3739 images) is available in the online journal.

Peculiar spectra identified by a visual comparison of best-matching hybrid templates with high-quality SPHEREx spectra. The example object shown is a known T8 (M. C. Cushing et al. 2014) with an extreme ≈4.2 μm CO2 feature for its spectral type. See Section 4.5 for more details.
