Notes. Shown are the GCS-III values and the derived values from this work (TW). We also add our values for log g, as it is also well centred on the solar value of 4.44. Two stars in italics are twins that have only been identified by using other line lists than the Ra09 list adopted in D12, see Sect. 4.2. Stars with a (∗) are considered the best twins in this analysis, see Sect. 6 and Fig. 11c.
