The abundances relative to solar determined for G200-40, 61 Cyg B as a function of their metallicity (Table   2), with 1 − σ error bars. The abundances for WD 1425 +540 are shown as a black line and blue shaded region (1 − σ error bars), as the [Fe/H] cannot be compared. The abundances have not been adjusted for relative sinking of different species, as we assume that the planetary material is accreting in build-up phase. Stars from Brewer et al. (2016) are included in orange for comparison, noting that typical errors are quoted as being between 0.01 and 0.04 dex. G200-40 has similar abundances to other metal-poor stars.
