N/O abundance vs. metallicity determined by the O3N2 parameter for different spaxels in the host of GRB171205A color coded according to distance from the center. The values are compared to star-forming galaxies in the SDSS (gray grid) and a sample of EELGs from Amorín et al. (2015). EELG metallicities were mostly determined using the T_e method (Amorín et al. 2015), while for the SDSS galaxies we used the same O3N2 calibration as for the spaxels in the host.
