Projected distance to the nearest companion d_nc, in Mpc, with respect to the tidal strength of the central galaxy on the system Q_A. Contour lines correspond to all the galaxies in the SIP and SIT; green triangles and orange hexagons indicate galaxies in the SIT and SIP, respectively, from MaNGA data. The horizontal solid black line delimits the grey shaded area with d_nc ≤ 100 kpc that we use to delimit close pairs. Within this area, the vertical solid black line at Q_A  =   − 2 is used to identify interacting galaxies, following Vásquez-Bustos et al. (2023).
