\caption{Effective temperatures (K) of the ``average'' components of \AD, \VZ, and \WZ.
The $V_0$ magnitudes and the $(b-y)_0$ and $c_0$ indices are based on the 
out-of-eclipse $uvby$ standard indices from CVG08.
The 2MASS observations ($J,H,K_{\rm s}$) were obtained at phases 0.216 (\AD), 0.181 (\VZ), and
0.495 (\WZ), respectively. For \WZ, the $V$ magnitude was calculated
from the value outside eclipses and the $y$ eclipse depth at phase 0.495. 
$A_{\rm V}$ is the adopted visual interstellar absorption.

M06, Masana et~al. (\cite{masana06}).
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 $(V-K_{\rm s})$.
