Median scaling relations for all galaxies. In the third column, the gray dashed line is the median curve from Barrera-Ballesteros et al. (2016) for 653 MaNGA galaxies. The gray line shows the 80% contour of Barrera-Ballesteros et al. (2016) for MaNGA galaxies with log M_★/M_⊙ < 9.2. The dotted lines in the last panel represent lines of specific SFR at 0.01 and 1 Gyr⁻¹. The thick gray line shows the star-forming main sequence relation obtained by Enia et al. (2020) for nearby spirals. Where data are insufficient for a median curve, only uncertainty bars are plotted.
