a) Mean (V,Ks) absolute pseudomagnitudes of field dwarf stars as a function of spectral type; b) open circles: (V,Ks) pseudomagnitudes of 280 Pleiades stars located at less than 0.84 mag (3 times the Gaussian dispersion of Fig. 3) from the Pleiades barycentric distance modulus. Hipparcos stars are identified with larger filled circles, superimposed our main sequence model shifted at the Pleiades distance.
