Abstract:
High resolution spectra of 5 giants, including a horizontal branch
star, of the metal-rich globular cluster 47 Tucanae were obtained with
the UVES spectrograph at the 8m VLT UT2-Kueyen telescope.
The atmospheric parameters (Teff, logg, [Fe/H], vt) were derived from
VIJK photometry and spectroscopic data based on Fe I and Fe II lines.
Description:
Equivalent widths (EW) measured for Fe I and Fe II lines using IRAF
task SPLOT and DAOSPEC. Column one gives the wavelength, column two
the atomic species. Columns three and four give the excitation
potential (EP) and gf-values, respectively. Columns 5-9 give the
measured equivalent widths for the five stars of the sample using
IRAF, while Columns 10-14 give the equivalent widths obtained using
DAOSPEC.
