... is present for the silicon abundances, as can be seen from Fig. 4. For this reason, no correction is necessary and a value of ∆ log C6 = 0 was adopted for this abundance determination. This agrees with Holweger (1973) and, moreover, confirms the upper limit of ∆ log C6 ≈ 0.3 given in that work. For ...
