Fraction of SF classes as a function of the revised Hubble stage, classified based on the FUV (upper panels, in blue) and continuum-subtracted Hα emission (lower panels, in red). The subpanels correspond to SF classes A (only circumnuclear SF, top), B (SF at the bar ends, but not along bar, middle), and C (SF along bar, bottom). Error bars correspond to binomial errors. Indicated for each category is the number of analyzed galaxies within the bin (bottom row of numbers), and the number of identified cases in each SF class (top row of numbers). In the upper left corners the total number of analyzed galaxies (N_gal) are given.
