Metallicities and linear models for each galaxy in units of [dex/R_eff], labelled accordingly. The colour code is the same for all galaxies, such that the abundances analysed with the upper branch of PG16 are represented in black and those calculated using the lower branch in blue. Additionally, green outlined markers represent DIG-dominated fibres in each galaxy. The red lines are models that consider all fibres, and the blue lines represent models with no DIG fibres. Grey lines represent resulting parameters from different iterations of the MCMC fit. Effective radii in the NUV-band are used. NGC 6946 has been additionally fitted with a piecewise linear function. The metallicity gradients for the rest of the sample can be found in Appendix G.
