Table 5: Parameters and standard errors for the base light curve solution obtained by a simultaneous fit. B is polar surface brightness, f1 and f2 are the fill-out factors $f_{i}:=\frac{\Omega ^{{\rm I}}-\Omega _{i}}{\Omega ^{{\rm I}}-\Omega ^{{\rm O}}}$, with $\Omega ^{{\rm I}% } $ and $\Omega ^{{\rm O}}$ the Roche potentials of the inner and outer critical surfaces. S and V denote surface area and volume and <tex2htmlcommentmark> k=R2/R1 is the ratio of the mean radii. a is the semimajor axis in solar radii, and $\protect\gamma$ is the systemic velocity in km s-1.
