Validation of the automated SPHEREx spectral types compared with literature spectral types for known ultracool dwarfs (blue circles or field objects, rightward purple triangles for known peculiar UCDs) and for photometric ultracool dwarf candidates with spectral type estimates in the literature (upward green triangles). The thick, dashed line represents the 1:1 relation and the thinner dashed lines represent the median absolute deviation (1.5 subtypes). A random jitter of 0.3 subtypes was added to both spectral type dimensions to improve visibility. See Section 4.3 for more details.
