Notes.(a) (1) Gaia EDR3 (Gaia Collaboration 2021), (2) Bailer-Jones et al. (2021), (3) TIC v8.2 (Stassun et al. 2019), (4) 2MASS (Skrutskie et al. 2006).(b) A systematic error of ~100 K is associated with the absolute calibration of the instruments, as in Kawauchi et al. (2022). This term is dominant compared to the random error from the fitting procedure.
