A CRITICAL LIST OF VOIGT-FITTED EQUIVALENT WIDTH MEASUREMENTS BASED ON THE SOLAR FLUX SPECTRUM

Equivalent widths of around 570 carefully selected absorption lines in the solar flux spectrum have been measured, using the Solar Flux Atlas from 296 to 1300 nm by Kurucz et al. The equivalent widths were derived from Voigt functions fitted to the selected line profiles in the Solar Flux Atlas. The measurements were used to determine two sets of solar log gf-values; one set is based on the solar model in the 1979 model grid by Kurucz and the other set on a similar 1990 solar model, also by Kurucz, using revised metal abundances by Anders and Grevesse. The data provide a homogeneous, high-precision reference for studies of differential stellar abundances based on equivalent widths, using the solar flux spectrum as the standard.
