Comparison of values for effective temperature T_eff (panel a), surface gravity log g (panel b), microturbulence ξ (panel c), and projected rotational velocity v sin i (panel d) as derived in the present work with previous studies: Fraser et al. (2010, black symbols), Simón-Díaz et al. (2017, blue), Markova & Puls (2008, red), and Searle et al. (2008, green). In cases in which an object is present in two or multiple studies the values are depicted by diamonds and connected with dotted lines. The symbols for HD 183143 and HD 119646 are marked by open symbols. For better visibility, the mean uncertainties are indicated in the lower right corner.
