The light curves are analyzed using the Wilson-Devinney light curve synthesis code, and the new geometric and photometric elements are derived. These elements, combined with the available spectroscopic data, yield the absolute system parameters, which make it possible to construct a model of the system.</style></abstract></record></records></xml>
