HRD for all 885 stars from the PTPS sample with uniformly determined parameters. Theoretical evolutionary tracks (Bertelli et al. 2008, 2009) for stellar masses of 1, 2, and 3 M_⊙ and two metallicities are presented as well. Newly assigned luminosity class is coded with a shape: triangles indicate dwarfs; rectangles indicate subgiants; and circles indicate giants. The gravitational acceleration at stellar surface – log g is colour coded.
