Histogram of the flux ratios in -band, corrected for galactic and internal dust extinction. The corrections are different for the bulge and the disk. The histograms for the S0s (full line), and the S0/a galaxies (dotted line) are based on the NIRS0S sample. For spirals the lines for Sab-Sbc (full red line) and later than Sc (dashed red line) are drawn using the OSUBSGS sample. This figure was originally published by Laurikainen et al. [27].
