Comparison of atmospheric parameters: HERMES versus spectroscopic surveys. The top, middle, and bottom panels show the comparison of effective temperatures, surface gravities, and metallicities. The HERMES values are on the x-axis, and the spectroscopic surveys are on the y-axis, with Andrae et al. (2023) in red, APOGEE DR17 in blue, and Gaia DR3gspspec in green. Each target is shown by a different symbol, as indicated in the middle panel legend. The Andrae et al. (2023) values show the better overall agreement, and largest overlap, with HERMES.
