Stars in our sample with estimated parameters from ATHOS in solid data points and Xiru in open circles. Blue data points are known Ba stars, red are carbon-enhanced stars, and green are “other” stars. Floating error bars are for Xiru (black) and ATHOS (green). Cool giants are in the upper right, and warm dwarfs are in the lower left. Top: Kiel diagram, with ATHOS operational limits as the dashed gray box. BOTTOM: Metallicity vs temperature for this subsample, with ATHOS operational limits as the dashed gray box. Colors are the same as in the top panel.
