 Table~\ref{tbl-OBecl} is presented in its entirety in Appendix A. The columns are:
the variable name, the HD number, the HIPPARCOS number, the HIPPARCOS variability flag, the variability type we assigned
in this study, the HIPPARCOS period (if any), the new periods found in this study 
(2~columns, for a possible alternative period), the periods found by \citet{koen:2002} (if
any), the $Hp$ magnitude, the mean amplitude calculated here according to Eq.~(\ref{eqs}) and the spectral type
according to the Vizier database.
