\caption{Line parameters for $\nu$~Gem: Next to the
  peak heights for the V and R peaks also the intensity of the central
  peak is given, when a triple-peaked profile was present (C
  peak). The radial velocities correspond to the local minima (modes)
  in these lines (for H$\alpha$ of the central depression). The
  typical error is 11 and 3\,km\,s\,$^{-1}$ for the {He}{\sc i}\,6678
  measurements in the coud\'e and {\sc Heros} data, respectively, and
  about 1 and 0.2\,km\,s\,$^{-1}$ for the much sharper H$\alpha$
  absorption core.}\\
