Histogram (normalised) for distribution of clouds with respect to Galactocentric radius (top) Galactic height (z_gal) (middle), and heliocentric distance (bottom). The histograms represent the ratio of clouds in each bin to the total number of clouds in all the bins. The bin width is 1 kpc for the heliocentric distance and Galactocentric radius plots, and 1 pc for the z_gal histogram. Blue represents the VC sample and orange represents the MR sample. The cloud morphologies from top to bottom represent ring-like clouds (Ring), elongated clouds (Elon), concentrated clouds (Cone), and clumpy clouds (Clumpy).
