Abstract
Errors and inconsistencies still present in the program WINK have been detected and corrected. Modifications of the program have been implemented in order to improve the effectiveness of the model during the solution of the inverse problem of finding the parameters of a system from the light curves. Other modifications are introduced in order to extend the validity range of the model to closer and more deformed systems. After the introduction of the modifications, the WINK solutions for such systems become much closer to the solutions produced by models which are more realistic geometrically (eg. the Wilson-Devinney model) than the solutions produced by the original WINK model.
