Notes. Symbols √ (*) in the status column denote that their absolute magnitudes and intrinsic colors dereddended by the parallax from Gaia DR2 data are consistent (inconsistent) with the temperatures derived from optical spectra or theoretical predictions (see Ramsay 2018). For BLAPs from Ref. (3), the symbols ⇑ denote confirmed status, and ⊙ denote high-confidence candidates. (1) Pietrukowicz et al. (2017), (2) Kupfer et al.
