We introduce new software for the modeling of exoplanet transit light curves. The technique is based on the aperture cross correlation between the light changes and the diffraction pattern of the apertures representing the eclipsing binary components (Kopal 1977; Kopal & Demircan 1978), where in the present case the eclipsing component is considered to be a transiting exoplanet. The software finds the best parameters including the fractional radii of the exoplanet and the host star, the inclination and eccentricity of the orbit, the longitude of periastron, limb-darkening coefficients of any degree, and the transit time, yielding the lowest chi(2). Parameter uncertainties are calculated with the jackknife method. We compare results for selected exoplanet transit light curves against those available in the literature.
