Notes. From left to right the columns give the name, galactocentric distance, right ascension, declination, pulsation period, and zero-phase reference epoch of maximum light in the V band. Column 7 lists the iron abundance available in the literature. Columns 8–11 show the number of optical spectra used for each spectrograph: NF, FEROS; NH, HARPS; NU, UVES; NS, STELLA. The last column lists the total number of spectra per target.
