The Galactic population components and their structural parameter values

The Galactic population components and their structural parameter values have been analyzed using the data of three-color photometry and modem starcounts calibrated recently in the seven Baset fietds M67U, SA51, SA71, SA82, SA94, SA107 and NGC6171. It is an important part of studying the Galactic structure all-sidedly and constructing a unique Galactic model.
