Absolute dimensions
===================

Combining the results of radial velocities and light curve analysis we have calculated the absolute parameters of the stars. The separation between the components of eclipsing pair is calculated as $a$=15.98$\pm$0.07 R$_{\odot}$. The fundamental stellar parameters for the components such as masses, radii, luminosities are listed in Table5 together with their formal standard deviations. The standard deviations of the parameters have been determined by using the [JKTABSDIM[^4]]{} code, which calculates distance and other physical parameters using several different sources of bolometric corrections [@sou05]. The masses for the primary and secondary star are consistent with F2$\pm$0.5V and F7$\pm$0.5V stars.
