Radial profiles of Σ_SFR for all nine galaxies in sample after removal of diffuse background. The x-axis presents the galactocentric radius normalised by r₂₅ (bottom) and in arcsecs (top). The y-axis presents Σ_SFR in units of 10⁻³ M_⊙ yr⁻¹ kpc⁻² (the scaling is performed for comparison with radial plots from original unsubtracted data in Fig. D.1). The brown and black curves denote Σ_SFR(Hα + 24 μm) and Σ_SFR(FUV + 24 μm) respectively obtained from the data where diffuse background is subtracted from the SFR tracers. The magenta and orange curves denote Σ_SFR(Hα + 24 μm) and Σ_SFR(FUV + 24 μm), respectively obtained from the diffuse background maps of the SFR tracers.
