Effective temperatures for stars in the works of Houdebine et al. (2019) and Kuznetsov et al. (2019) compared to our values after computing them with our procedure (top panel). In gray, the line represents a one-to-one relation. All the stars can be found near this one-to-one relation, indicating a good agreement between these values. In the bottom panel, combined errors are shown together with a dashed line that indicates the value for 3σ.
