Stacked spectral residuals of our young (<300 Myr; left) and old (≥300 Myr; right) benchmark targets with M8–L2, L2–L6, L6–T0, and T0–T6 spectral types based on Sonora Diamondback model fits. We highlight the absorption bands of key atmospheric species whose wavelengths line up with several prominent residual features.
