Position of the analysed stars (red ellipses) in the T_efff-log(g) diagram (upper panel), HRD (middle panel) and sHRD (lower panel). The error ellipses outline 1σ--uncertainties, the stars are identified by their ID number according to Table 1. Additionally, evolutionary tracks of Ekström et al. (2012) for non-rotating stars at solar metallicity Z = 0.014 are indicated (25 M_⊙: solid, 20 M_⊙: dashed, 15M_⊙: dotted line). The HRD includes isochrones from Ekström et al. (2012) for logτ_evol(yr) = 6.0, 6.4 and 6.7 (blue dash-dotted lines, left to right). In the sHRD lines of constant log g are indicated by dotted magenta lines. In addition the sHRD shows evolutionary tracks for rotating stars (υ/υ_crit = 0.4) in blue for comparison.
