The new light curves are analyzed with the WD code and new geometric and photometric elements are derived. These elements are combined with the available spectroscopic data to yield the physical parameters of the system. The agreement between the spectroscopically and photometrically determined mass ratios of eclipsing binaries is also discussed.</style></abstract></record></records></xml>
