I am a member of the PLANET collaboration which looks for 'anomalies' in the ongoing galactic microlensing events. These 'anomalies' include binary sources and lenses (especially a star with a planet), a finite extent of the source and its brightness profile, and rotation effects in the observer (earth around sun), the lens, and the source. To fit light curves which involve binary lenses, I have developed a code, which now works also for extended sources, and which also includes all rotation effects. For given observed data I work on the extraction of information which includes discussing ambiguities and uncertainties in the model parameters and in the resulting physical quantities (lens masses, velocity and distance...).
