J/A+A/434/275) and II (2005A&A...434..301D) we performed the first determination of the age of the Galactic thin disk from Th/Eu nucleocosmochronology. The present work aimed at reducing the age uncertainty by expanding the stellar sample with the inclusion of seven new objects. The Th and Eu abundances used in the dating procedure were obtained through spectral synthesis, and to perform the synthesis it was necessary to know the atmospheric parameters and chemical abundances of contaminating elements. Description: The file table5.dat contains all the equivalent widths of lines used for atmospheric parameters and abundance determinations of contaminating elements. Some lines have not been effectively used in some stars; these have equivalent widths equal to 0.00 in the file. All equivalent widths are presented in milli-Angstroms.
