\label{larson_figure} Correlations between the properties of molecular clouds in M83. (a) This panel shows the correlation between the virial and luminous mass estimates for the clouds, with the color of the plotting symbol representing the distance from the center of the galaxy. The two mass estimates correlate well, particularly at the high mass end, where the signal to noise is highest. (b) The size-line width relationship for clouds in M83 shows good agreement with the relationship measured in the Milky Way (solid line). However, the clouds in the center of galaxy are displaced above the relationship. (c) The mass-radius relationship shows most clouds have surface densities close to that of the Milky Way, but clouds in the galaxy center show higher surface densities. (d) The correlation between surface density and velocity dispersion on a 1 pc scale ($\sigma_v^2/R = \sigma_0^2$) (here represented by the square of that quantity, $\sigma_v^2/R$)  shows that most clouds agree well with the locus of self-gravitation.
