Azimuthally averaged mean NUV (left) and FUV (right) luminosity profiles (solid lines), in bins of numerical Hubble type, obtained from the 2D bar stacks shown in Fig. 1. The dashed lines correspond to the surface brightness cut along the bar major axis. The vertical dotted line indicates the bar end. FUV luminosities are converted to Σ_SFR (right y-axis of the right panel) using Eq. (1).
