GALAH DR4 spectroscopic parameters and abundances

Southern-sky high-resolution optical spectroscopy of variable stars from GALAH DR4 (Buder et al. 2025, HERMES on the AAT): effective temperature, surface gravity, [Fe/H], radial velocity, rotation, 3D NLTE lithium and up to 30 element abundances. GALAH's quality flags are shown in words, including the Hα-emission and single- and double-lined binary flags common among variables, with whether each star meets GALAH's recommended quality cut.
