Notes. Model (A) results are shown in Col. 2, model (B) results are shown in Col. 3, and the DMA results are shown in Col. 4. Column 5 shows the range of results from the references in Col. 6. The atmospheric parameters and abundances of model SAT(A) were calculated concurrently, while the IRFM effective temperature (Alonso et al. 1996b) and parallax surface gravity were used in model SAT(B).
