Comparison between published spectral types for the objects that have neither SIMBAD nor Gaia associations but are present in either UltracoolSheet (Best et al. 2024a), Brooks et al. (2024) or Burgasser et al. (2024b), with our best estimates done using the VOSA spectral fit based on the BT-Settl model grid (circles), using the nearest UltracoolSheet neighbors in the two-color plots akin to Figure 7 (squares), or by using UltracoolSheet objects with similar W 1 – W2 colors (stars). The error bars correspond to the 96% (2σ) confidence limits of the corresponding estimations. Two significant outliers in the upper left corner are CWISE J220134.02-041609.5 and CWISE J230252.77-131458.0, which both have very large χ² values in Brooks et al. (2024) indicating bad fits there, so we consider our late type estimations for them to be more correct. The VOSA effective temperatures for three objects from Burgasser et al. (2024b) agree well with the published values, while their spectral types are underestimated (green circles below the equality line) due to differences in the temperature to spectral type mapping for subdwarfs from the Pecaut & Mamajek (2013) ones that we used.
