Abstract :
[en] We present an easy way to simulate and fit light curves of microlensing events for the particular case of binary stellar systems with occultation, using semi-automatic graphical interfaces written in IDL language. Gravitational microlensing effects are known to induce light amplifications of the background source and, until now, photometry has been the main technique used to study this phenomenon. A good software, capable to fit multiple parameters of the observed light curve of the microlens event, would allow astronomers to obtain important informations about the physical characteristics of the objects studied. The developpement of such a software is focused to some peculiar case, briefly treated in Sec. 1. The software, written following the parametrization described in Sec. 2, is presented in Sec. 3 and 4.
