\caption{Characteristics of the B stars in the sample of \citet{La97} depicted in Fig.~\ref{fig:closeupBstars}. The "observed'' absolute magnitude $M_V^{\rm H}$ is calculated from the Hipparcos parallax $\pi_{\rm H}$ (in mas), and is corrected for interstellar extinction and the presence of spectroscopic companions. The predicted absolute magnitude $M_V^{\rm SK}$ is derived from the spectral type according to the calibration of \citet{SK82}, if necessary through interpolation (note that they have a special section for Be stars). $v \sin i$ is in km~s$^{-1}$.}\label{tab:Bstars}
