Star formation rate as a function of the stellar mass of the galaxy. The grey circles denote all the galaxies, blue plus signs mark the cSB galaxies with the circumnuclear regions of the SF BPT type, blue crosses show the cSB galaxies with the circumnuclear regions of the SF+INT BPT type, red plus signs are the cSB galaxies with the circumnuclear regions of the INT BPT type, and red crosses show the cSB galaxies with the circumnuclear regions of the AGN BPT type. The green square is the MaNGA galaxy M-8454-12702. The SFR – M_⋆ relations for the MaNGA galaxies obtained by Cano-Díaz et al. (2019) are shown by the dashed line for the early-type spirals and by the solid line for the late-type spirals. The dotted line denotes the SFR – M_⋆ relation for the present-day epoch from Speagle et al. (2014).
