Fig. 8


Examples of a number of different synthesised neutral and ionic lines, using our multiple cross-matched literature log (gf) and rest-wavelength values, compared against the observed Kitts Peak FTS solar flux spectrum (black). Panels a and b: examples where the majority of literature log (gf) values provide good fits to the observed line profile, with the exception of one value that systematically differs. Panel c: a similar example but for Si II, a species with relatively few usable clean lines in the visible spectrum. In addition, the central rest wavelength does not match the observed spectrum. Panel d: an example where literature log (gf) value differences can reach as high as Δlog(gf) ≈±0.5 dex, and also a slight offset between observed and theoretical rest wavelengths. Panels e and f: examples of the so-called missing and unobserved lines. Panels g and h: a number of examples of lines with inaccurate log (gf) values when compared with stellar spectra.
