Comparison between nitrogen abundances derived with the automated fitting method (vertical axis) and the method described in Sect. 3 (horizontal axis). Dotted lines indicate the nitrogen baseline abundance of LMC stars. The dashed line shows the 1:1 relation. The observed stars are marked with their VFTS ID. Except for two stars the two methods agree within 1σ. Note that ξ_m is allowed to vary in the automated method, while ξ_m is fixed at 10 kms^-1 for the measurements in this paper (see Sect. 3.4).
