Comparison of the AMBRE/FEROS V_broad upper limits with the measurements of Frémat et al. (2023), derived from Gaia/RVS DR3 spectra. The horizontal red and blue dashed lines refer to the F23 measurement limit and to their low- V_broad domain, where overestimated values are suspected (5 and 12 km/s, respectively). The colour coding represents the F23 V_broad relative uncertainty. The inset focuses on lowrotating F23 stars having a V_broad relative uncertainty lower than 20%.
