Radio-FIR correlation diagram for our Magellanic-type and peculiar galaxies (diamonds), as well as interacting objects (squares) and bright spiral galaxies (asterisks). The surface brightness a) and luminosity b) at 4.85 GHz (6 cm) and at 60 μm are used, respectively. The solid line is a bisector fit to all galaxies, while the dashed lines represent simple X vs. Y and Y vs. X regressions. Error bars are marked just for a few objects for example’s sake.
