Geneva evolution tracks for non-rotating stars without magnetic field for the metalicity Z = 0.014 (Mowlavi et al. 2012). The grey point is the luminosity value derived based on Gaia DR2 without the bolometriccorrection and dereddening. These corrections are applied for the black point. The colour of the evolutionary tracks distinguishes the A- and B-type stars. The vertical line shows the upper T_eff limit determined by the best fit of the spectra. The column on the right-hand side of the graph denotes the stellar masses in M_⊙.
