Notes.Pearson correlation coefficients rc and bisector slopes b, log(Y) ∝ b log(X), between the 20 cm synchrotron (X) and various FIR bands, bolometric FIR, and total neutral gas (Y). The number of independent points, n, and the Student’s t-test, t, are also indicated for each correlation. Also shown are the correlations between the gas surface density ΣGas and the star formation surface density ΣSFR, the total magnetic field Btot in logarithmic space. The nucleus was excluded before cross-correlating.
