Description

Space densities and parameters of z-distribution for ten star groups in the Hertzsprung - Russell diagram (A - K3, A - G4, A - G5) were determined. Data from the Abastumani two-dimensional spectral classification catalogue, and a statistical procedure of data processing, allowing to take into account uncertainties of observational data as well as the catalogue selection effect, were used. The study of the space distributions allowed to carry out an independent estimation of a luminosity dispersion for different sequences in the Hertsprung - Russell diagram
