Line: Fe I - λ6151.6

Quality assessable? Yes  |  Robust against analysis method? Yes

Line considered quality assessable if log(gf)grid and log(gf)cog within error of each other. Line considered robust against analysis method if log(gf)grid and log(gf)cog within 0.04dex of each other.

log(gf)grid: -3.27 ± 0.03      log(gf)cog: -3.27 ± 0.03

Line profile plots per G-type benchmark star

Information Radio buttons can be used to choose which database log(gf) values and line profiles to view. Interactive plot controls can be found to the top right of plotting panels.

Top left panel: Points represent the individual stellar log(gf) values plotted as a function of effective temperature. Lines represent the mean log(gf) values and the literature log(gf) values.
Shaded areas represent the uncertainty associated with a given log(gf) value.

Remaining panels: Observed line profiles are shown by black dotted lines for each of the 7 FGK-type benchmark stars. Synthetic line profiles, calculated using the mean log(gf) values and the
literature log(gf) values, are shown by the solid coloured lines. Shaded areas represent the uncertainty in line profile flux due to the uncertainty in the corresponding log(gf) values.
