Star formation rate vs. stellar mass in the J-PLUS DR1 Full sample (bullets) in comparison with previous work based on Hα imaging. Left panel: results from Hα3 data in the Local Supercluster area (circles, Gavazzi et al. 2013), and for LSB galaxies at z ≤ 0.017 (triangles, McGaugh et al. 2017). Right panel: median log SFR as a function of stellar mass in the Local Supercluster and the Coma cluster derived by Gavazzi et al. (2015). The red solid line marks the median log SFR estimated from the Full sample.
