Upper panels: classical HRD (left) and the v sin i distribution as a functionof log Teff (right) for the sample stars plotted against the current Geneva grids. The observed v sin i values account for the effects of macroturbulence; the model Vrot was scaled by π/4 to account for (average) projection. Lower panels: ratio of evolutionary and spectroscopic mass as a function of log L∕L⊙, after using the rotating and non-rotating Geneva tracks to calculate Mevol(HRD). The shaded area corresponds to the typical 1σ uncertainty in the individual mass ratios centred at unity. Vertical dashed lines indicate the luminosity bins as discussed in Sect. 6.1. Numbers from 1 to 6 denote the outliers as discussed in Sect. 6.1 and Appendix B. Symbols and colour coding as in Fig. 12.
