tokens: The Liège team acknowledges support from the Fonds de la Recherche Scientifique (F.R.S/FNRS) including especially an F.R.S/FNRS Research Project (T.0100.15), as well as through an ARC grant for Concerted Research Actions financed by the French Community of Belgium (Wallonia-Brussels Federation), and an XMM PRODEX contract (Belspo). We are particularly grateful to Reinhold Haefner for having made his IBVS data available and to Ella Antokhina and Igor Antokhin for discussions on the photometric solution. EG is greatly indebted to Stephanie Wachter and Suzanne Tourtelotte for having spared no pains in facilitating the interaction with the YALO archives. We are grateful to I. Stevens, H. Sana, Y. Nazé, J.-M. Vreux, and M. da Silva Pires for taking some of the spectroscopic data or for discussions on earlier versions of this work. We thank John Hillier for making his code available.
