Table 5.

Box widths (W) used for box integration, radio beam FWHM converted to physical scales, assumed flux tube radius (R0) used for CR transport modelling for each galaxy; SFR, SFR surface density, and average equipartition magnetic field strength in the galactic disk for individual stripes; gravitational pull for central and outer stripes (as we assume the gravitational potential to be symmetric, there is no distinction for left and right stripes).
