Spatially resolved main-sequence relation (rMSR) between the surface density of stellar mass (Σ_*) and the surface density of star formation rate (Σ_SFR) for star-forming knots in NGC 4809/4810. The sizes of the markers correspond to the sizes of the knots. The gray contours indicate the distribution of Σ_* and Σ_SFR of 54 star-forming galaxy pairs selected by Steffen et al. (2021) in the MaNGA survey. We also provide the star formation knots around SN2011jm (red edgecolors) and at the interaction area (blue edgecolors), which are the same as in Fig. 1. The dashed lines represent different specific star formation rate (sSFR, Σ_SFR/Σ_*) levels.
