We present a software to determine the size of an exoplanet and the inclination of its orbit to the plane of the sky from the light curves of transits. The computational code was tested by several transits of planet TrES-3b, the data on which were taken from an archive, as well as acquired at the Caucasian Mountain Observatory of the Sternberg Astronomical Institute (CMO SAI). We also present the results of processing the observations of three planets (HAT-P-19b, KOI-196b, and WASP-60b) carried out at the CMO SAI. The comparison of our estimates of the radius and the orbital inclination of the planets to those obtained earlier by other researchers shows that the data agree within the error limits, if the light curves, which we retrieved, are of sufficient quality (for HAT-P-19b and WASP-60b) and the coefficients' values (specified in accordance with theoretical models) are fixed in the limb-darkening models. The sensitivity of the results to the limb-darkening model parameters of a stellar disk is discussed. Specifically, the degeneracy by the darkening parameters and the planet-to-star distance during the transit has been demonstrated. [ABSTRACT FROM AUTHOR]
