Sample characteristics. Top: distribution of effective temperatures as a function of H-band magnitudes in the stellar sample. The colors indicate the source of the temperature measurement: C22 (Cristofari et al. 2022), C23 (Cristofari et al. 2023), M21 (Marfil et al. 2021), G14 (Gaidos et al. 2014), and F18 (Fouqué et al. 2018). Middle: distribution of stellar masses and distances. Bottom: distribution of metallicities and effective temperatures.
