Left: Cumulative distributions of the molecular mass surface densities from the full cloud sample. The different colors represent the different environments. The y-axis is the fraction of clouds with a surface density greater than a given value. All distributions are normalized by the total area of their specific environment, A. Middle: Same as the left plot, but only considering barred spiral galaxies and excluding disks. Right: Same as the left plot, but only considering barred disk galaxies and excluding spirals. We removed the central region from the PDFs due to overlapping cloud bias.
