Same as Fig. 2 but considering only AMBRE stars with a fully derived V_broad (i.e. excluding upper limits) and high-quality measurements in both catalogues (V_broad relative uncertainty less than 20%). The black-dashed line denotes the one-to-one relation for visual reference. For clarity, six extreme F23 stars with V_broad>50 km/s are not shown (see text for details, including a discussion about the bias and dispersion associated to this comparison).
