Metalicity gradient obtained from the extraplanar H II-regions from Howk et al. (2018a) and from ASASSN-14jb, as a function of the vertical distance to the disk normalized by the isophotal radius R₂₅. The metallicity offset from ASASSN-14jb was obtained from measurements of the Fe II λ5018 line pEW and the calculated mean oxygen abundance of the host, ESO467-G051, from the O₃N₂ diagnostic. We also estimated the oxygen abundance at the supernova position extrapolating the vertical gradient obtained from our H II-region abundances using the regions at any azimuthal position, dubbed “linear”, and from a two dimensional model, dubbed “planar”, which are marked as a black triangle and square, respectively.
