Biases of the ParSES output for the pilot sample with respect to PASTEL (Soubiran et al. 2016; circles) and Tautvaisiene et al. (2020), shown as pluses, both collectively labeled “others”. Panel a: effective temperature in Kelvin. Panel b: logarithmic gravity in cms⁻². Panel c: global logarithmic metallicity relative to solar. Panel d: comparison between υ sin i results (inverse triangles) from the two independent methods ParSES and iSVD. The dashed line in each panel is again just a 45-degree line to guide the eye.
