Comparison of the stellar parameters (Cols. 2-5) for the Z06-star from five different spectroscopic studies (Col. 1).
| Reference | Teff (K) | log(g) (dex) | [Fe/H] (dex) | ξmic (km s−1) | [Mo/Fe] (dex) | [Eu/Fe] (dex) |
|---|---|---|---|---|---|---|
| Lecureur et al. (2007) | 4400 | 1.8 | −0.62 | 1.4 | 0.73 | 0.85 |
| Zoccali et al. (2008) | 4350 | 1.7 | −0.65 | 1.4 | 0.68 | 0.83 |
| Ryde et al. (2010) | 4250 | 1.5 | −0.69 | 1.4 | 0.58 | 0.81 |
| Johnson et al. (2014) | 4425 | 1.65 | −0.58 | 1.70 | 0.68 | 0.74 |

Notes. Note that the Ryde et al. (2010) stellar parameters are determined from an infrared, H-band spectrum of the Z06-star. We calculate the [Mo/Fe] and [Eu/Fe] (Cols. 6–7) using the methodology as described in Sect. 3, and use A(Mo)⊙ = 1.88 and A(Eu)⊙ = 0.52 from Grevesse et al. (2015). Eu has been decreased by 0.10 dex, since Forsberg et al. (2019) report possible [Eu/Fe] to possibly be systematically too high due to systematics in the stellar parameters. We lower it such that their overall thin disc, as seen in Fig. 2, goes through the solar value, also as described in Sect. 3.1.
