Using the widely known simplex method of minimizing the square of the dierence between the observed and theoreticaldensities, we have found the corresponding free parameters for globular clusters. As observational data we have taken mostlythe density proles constructed by [1] based on a combination of Hubble Space Telescope and ground-based data. One ofthe free parameters of our model characterizes the concentration of stars toward the globular cluster center. Errors for freeparameters of the model are calculated.
