Panel a: lower limit of the star formation rate, SFR_ll, as a function of stellar mass for MaNGA galaxies. The plus signs denote galaxies with ΔPA > 20° and with signs of an interaction. The circles denote galaxies with ΔPA > 20° and without signs of an interaction. The gray points mark galaxies with ΔPA < 20° from Pilyugin et al. (2019). Panel b: same as panel a but for the upper limit of the star formation rate, SFR_ul. Panel c: comparison between the SFR_ul and SFR_ll for those galaxies. The line is that of equal values.
