Very simplified and shortened version of Fig. C.1 as an example for NGC 4981. Light- and mass-weighted age and metallicity profiles along cut #2 (see Fig. 8) perpendicular to the bar major axis are shown. The width of the cuts is 4″ and bins are equally spaced every 2″ along the cuts. The two cuts #2 are averaged in the anti-parallel direction as shown in Fig. 8. Vertical lines mark the edges of the bar. Linear regression fits from the major axis to the edges of the bar are shown in green. The slopes of these fits are tabulated in Table 3 and plotted in Figs. 10 and 11.
