As in Fig. 8 but compared against the BRASS benchmark spectrum of 51 Peg (G2.5IV), observed using the Mercator-HERMES spectrograph (black). Panel a: multiple literature log (gf) values that all provide a good fit to the observed line profile. Panel b: only one literature log (gf) value out of four fits the observed line profile well. Panels c and d: a number of Fe I line log (gf) values with varying qualities of fitting to the observed profiles ranging from excellent fit to poor fit.  Kostyk (1982),  Fuhr et al.

The log (gf) uncertainty is ≥50% and calculated by NIST in the same manner as Kramida (2013), and  Blackwell et al. (1980).
