Table 2.

Fundamental stellar parameters estimated from the IGRINS spectra of six benchmark stars using our method and the literature compilation of stellar parameters (indicated by the lit subscript).

Notes. We list log g and [Fe/H] values as ‘–’ if there are no log g, [Fe/H] measurements in the literature (e.g., in the case of optical interferometric measurements as in Baines et al. 2021 or T_eff versus (V-K)₀ relation in Bessell & Brett 1988).
