Panel a: spectroscopic stellar mass of our galaxies, M_sp, as a function of their photometric stellar mass, M_ph. The points represent the individual MaNGA galaxies of our sample. The solid line is the linear best fit to those points. The dotted line indicates exact correpondence in the masses. Panel b: MaNGA stellar mass, M_ma, as a function of photometric stellar mass, M_ph, and panel c: MaNGA stellar mass, M_ma, as a function of spectroscopic stellar mass M_sp. The notations are the same as in panel a. Panels d–f: M_ph, M_sp, and M_ma as a function of the rotation velocity V_rot, respectively. The points denote individual galaxies, the solid line is the M_ph–V_rot relation (best fit), the long-dashed line is the M_sp–V_rot relation, and the short-dashed line is the M_ma–V_rot relation.
