[Sr/Ba] ratio of SDSS J0222–0313 (blue star for the LTE ratio and open circle for the NLTE value) compared to the CEMP sample from Hansen et al. (2016a, black diamonds) and Hansen et al. (2019, red squares), with [Fe/H ] < −2.0. Error bars for SDSS J0222–0313 are the uncertainties in [Ba/Fe] and [Sr/Ba]. We include the division (dotted lines) suggested by Hansen et al. (2019) in their Fig. 7. The star SDSS J0222–0313, being a CEMP-s star, would be expected to have a lower [Sr/Ba] value due to its high [Ba/Fe].
