Description:
A collection of spectroscopic data of 4 Her at our disposal (RV and
spectrophotometric measurements) consist of spectra obtained at the
Ondrejov and Haute Provence Observatories. Table 1 summarizes the
measurements of radial velocities and line intensities carried out in
the red spectra. In Table 2 a list of the spectra and RV measurements
for the violet-blue region is given.
