Histogram of velocity dispersion σ_υ (a), radius (b), CO luminosity (c), and virial mass (d) for SMC clouds (gray histograms) and for clouds in the SW (green), NE (red), and WG (yellow) regions. These histograms belong to the well-resolved clouds with R ≳ 2.2pc and S/N ≳ 5. The vertical dotted line in each panel indicates the median of the parameter given in Table 3 for the total sample. These parameters were corrected for sensitivity and resolution biases from observations at 9 pc resolution.
