We present the result of the analysis of the point-by-point correlation between the radio continuum (RC) and CO intensities from kpc to sub-kpc scales in 22 BIMA SONG galaxies and the point-by-point correlation at sub-kpc scales between the RC, CO and 24 μm-IR emissions in 6 galaxies for which Spitzer images have been recently released. We found that there is no significant variation of the slope and the scatter of the correlations at this spatial resolution. All three correlations are comparably tight with scatter of less than a factor of two.
