The $V_0$ magnitude and the $(b-y)_0$ and $c_0$ indices are based on the out-of-eclipse $uvby$ standard indices from Table~\ref{tab:bkpeg_std}. The 2MASS observations ($J,H,K_{\rm s}$) were obtained at phase 0.879. The results from A96 are based on their $uvby$ calibration, those from RM05 on their $uvby$, $(V-J)$, $(V-H)$, and $(V-K_{\rm s})$ calibrations (in that order); the calibration by M06 is for $(V-K_{\rm s})$.} \vspace*{-2mm} \tablebib{A96 = Alonso et al.
