Notes.
Abundances in the present-day solar photosphere from Asplund et al. (2009) except for Ar for which we take Lodders (2003).
Calculated from S ii column density and assuming S/O = −1.64 (ionized gas value from Péquignot 2008).
Argon abundance is taken from A03 and L04, with 12 + log (Ar / H) = 4.20 ± 0.15 (Table 5).
