Notes.
The magnitude limits are placed considering r magnitude in all samples except for the Hα dots, where R magnitude was used instead. In the GAMA and SDSS samples and comparisons, Petrosian magnitudes were used. For the Yang et al. (2017) sample (who used cmodelmag magnitudes) and for the Hα dots sample (circular apertures), we used AUTO apertures in the J-PLUS comparisons.
In the blueberry galaxy, green pea, and Hα dot comparisons, we restricted the J-PLUS sample to compact or semicompact objects to reproduce their selection criteria.
