Abstract

Photoelectric lightcurves of five eclipsing binaries, suspected of having undersize subgiant secondaries (i.e. sd-d systems), have been reanalyzed by means of Wood's model in order to obtain homogeneous photometric elements. FL Lyr appears to be a normai main sequence detached system ; XX Cep and probably V 548 Cyg turn out to be common sd-systems, whereas only for TW Cas and AD Her might the sd-d classification be retained.
