Comparison of the h = 0, NLTE calculations of Takeda et al. (2005) and this work. The results from Takeda et al. (2005) for Teff ≥ 4500 K are shown in pink and light blue, while the results from this work are shown in red and blue for Teff ≤ 4750 K. The result is shown both for the smaller correction of [ Fe / H ] = −1 (blue and light blue) and the larger effect of [ Fe / H ] = −2 (red and pink). The calculations for all three S lines are shown, 9213 Å (dashed lines), 9228 Å (solid lines), and 9238 Å (dotted lines). In all cases log g = 1 and [ S / Fe ] = 0.2 are assumed. We note that Takeda et al. (2005) assumed a solar value of log ϵ(S) = 7.21, while here a value of 7.16 is adopted, so there is a difference of 0.05 in [S/Fe]. In the case of Takeda et al. (2005), vt = 2 km s-1 is assumed, but vt = 1.7 km s-1 in this work. These small discrepancies do not have a significant effect on the comparison.
