Notes. Column 2: d is the distance (Heesen et al. 2022); (3) r is the star formation radius as obtained from radio continuum (Heesen et al. 2022); (4) is the SFR surface density within r; (5) Beq is the total magnetic field strength estimated from energy equipartition (Chyży et al. 2007; Mulcahy et al. 2017; Heesen et al. 2023b, for NGC 2903 we use the B–ΣSFR relation); (6) p is the polarisation fraction at 1365 MHz (Heald et al. 2009); (7) v is the rotation velocity of the galaxy (Heesen et al. 2022); (8) i is the inclination angle (Heesen et al. 2022); and (9) SFR is the integrated star formation rate (Heesen et al. 2022).
