Radio-infrared correlation of 15 galaxies in the reduced Hi sample detected by IRAS at 60 μm. Left: correlation between flux densities. The solid line indicates the simple relation S_21cm = 0.01S_{60 μm}. The dashed line shows the correlation found by Yun et al. (2001) for the IRAS 2 Jy sample. The vertical line indicates their lower flux-density limit of 2 Jy. Right: correlation between intrinsic radio and infrared luminosities.
