Notes. (a)–(c) show three sets of cross-matched lines, (a) the Mn II pair have been correctly cross-matched by both the parametric and nonparametric methods, (b) the Cr I pair have been incorrectly cross-matched using the parametric method and not the non-parametric method, (c) the Fe II pair have been incorrectly cross-matched using the parametric method and not the non-parametric method, (*) cross-matched using Δ E = ±0.1 eV, and (**) cross-matched using Δ E = ±0.0005 eV.
