List of stellar parameters for our sample sources.

	(h m s)	( $^{\circ }$ ' '')	(K)	(cgs)		(days)			(%)	(kpc)
EP Lyr	19 18 17.5	+27 50 38	7000	2.0	-1.5			$0.51\pm0.01$	$3\pm0$	$3.2\pm1.0$

Note: Listed are the name, equatorial coordinates $\alpha$ and $\delta$ (J2000), effective temperature $T_{\rm eff}$ , surface gravity $\log g$ , and metallicity [Fe/H] of our sample stars. For the model parameters we refer to De Ruyter et al. (2006). Also given are the orbital period and the eccentricity (see references in Gielen et al. 2007; De Ruyter et al. 2006). The total reddening $E(B-V)_{\rm tot}$ , the energy ratio $L_{\rm IR}/L_*$ and the calculated distance, assuming a luminosity of $L_*=3000\pm2000$ $L_{\odot}$ .
