Distribution of PHANGS bar-like features (upper panels) and outer (arm-) features (lower panels) along the star-forming main sequence according to Leroy et al. (2019; gray solid line, extrapolated to larger and smaller stellar masses with a dotted gray line). Left panels: galaxies are colored by their classes (upper: A,B,C; lower: F,M,G,S) and opacity indicates the confidence of each classification. An example of the confidence range is indicated as grey scale bar in the left panels. Histograms indicate the distribution of galaxy stellar masses and SFRs for each class. Right panels: galaxies with deviations of one or more than one classes from the literature classification, as described in the text, are highlighted by their PHANGS class (colored filled symbol) and their corresponding literature class (colored open symbol). Colors and shapes are the same for the left panels. For comparison, galaxies with similar classification (grey points) as well as galaxies without a literature class (black plus) are shown. We note that among our galaxies none have literature classes SB and all literature flocculent classifications agree with PHANGS classifications. PHANGS armclass S does not have a corresponding literature class.
