Özet:

 We propose a line list that may be useful for the abundance analysis of G-type stars in the wavelength range 4080  6780 Å. It is expected that the line list will be useful for surveyslibraries with overlapping spectral regions e.g. ELODIESOPHIE libraries, UVES-580 setting of Gaia-ESO, and in particular for the analysis of F- and G-type stars in general. The atomic data are supplemented by detailed references to the sources. We estimated the Solar abundances using stellar lines and the high-resolution Kitt Peak National Observatory KPNO spectra of the Sun to determine the uncertainty in the log   values. By undertaking a systematic search that makes use of the lower excitation potential and   -values and using revised multiplet table as an initial guide, we identified 363 lines of 24 species that have accurate   -values and are free of blends in the spectra of the Sun and a Solar analogue star, HD 218209 G6V, for which accurate and up-to-date abundances were obtained from both ELODIE and PolarBASE spectra of the star. For the common lines with the Gaia-ESO line list v.6 provided by the Gaia-ESO collaboration, we discovered significant inconsistencies in the   -values for certain lines of varying species.
