Comparison of our r-band best-fit parameters with those from the multi-component photometric decompositions of the 3.6 μm images of the S⁴G galaxies (Salo et al. 2015). There are 65 galaxies in common between our sample and S⁴G. Left panels correspond to elliptical/bulge parameters: effective radius (top) and Sérsic index (bottom). Controversial bulges (see text) are plotted as grey dots. Middle panels compare the disc scale lengths for single discs (top) and truncated discs as classified by this work (bottom). Salo et al. (2015) only include single discs in their decompositions. Inner and outer disc scale lengths are distinguished in the case of breaks as blue and red dots, respectively. For the sake of clarity, the 1:1 axis proportion in the bottom panel has not been kept. The right panel shows the comparison of the bar lengths for the 19 galaxies classified as barred by both works. The use of two different disc components (an exponential and Ferrers) in the S⁴G fit explain the difference for NGC 5957 (grey dot).
