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.
Warning: log(gf)grid and log(gf)cog are not within 0.04dex of each other. Systematic differences between the log(gf)grid and log(gf)cog values may be caused by additional lines in the synthesis, which the curve of growth (cog) method does not account for. The quality of these additional lines has not been tested.
