The FORTRAN-4 programs for processing the data on the tracks registered by nuclear photoemulsions developed by the method of selective development are described. The method developed to control emulsion sensitivity in a wide range of charged particle ionization losses is used in the development of the emulsions exposed on board of the KOSMOS satellites. The characteristic granularity obtained in development of charged-particle tracks is used to develop algorithms of programs for calibration of emulsions and identification of charges of cosmic particles detected by the KOSMOS-1571 satellite. The algorithm of identification of multicharged particles is obtained for the first time. 6 refs.; 8 figs.
