AbstractWe used the Clark Lake Radio Observatory TPT array at a frequency of 57.5 MHz to survey a total of 133 galaxies, mostly late-type spirals; 68 galaxies were detected. Observed radio intensities S_obs_ are systematically lower than intensities S_extr_ extrapolated from measurements at higher frequencies. The ratio S_obs_/S_extr_ correlates well with the axial ratio of the observed galaxies and is smallest for edge-on g ...
