Notes. Column (1) Name of the galaxy; (2) inclination angle with respect to the line of sight; (3) distance; (4) path length; (5) integrated flux density at 144 MHz; (6) integrated radio spectral index; (7) mean magnetic field strength; (8) maximum magnetic field strength; (9) H I mass from Walter et al. (2008); (10) H2 mass from Leroy et al. (2009); (11) mean turbulent velocity dispersion for H I/H2 gas from Mogotsi et al. (2016). Other data are from Heesen et al. (2022).
The CO detections of NGC 3077 and 4449 were marginal, so that these galaxies were left out of the analysis of the ancillary data (Sect. 2.2); for NGC 5474 we have only an H I map and so omitted this galaxy as well for consistency.
