Normalized distribution of properties for GMAs in different galactic environments. Filled red stars, blue squares, green circles, and magenta triangles represent GMAs in the CNR, bar, spiral arms, and inter-arm regions, respectively. Median values of properties are indicated with open symbols. Error bars represent Poisson errors. In the panels, we plot the GMA (a) mass (Mc), (b) effective radius (Rc), (c) surface density (﹩{{\rm{\Sigma }}}_{{{\rm{H}}}_{2}}﹩), (d) velocity dispersion (σc), (e) SFR surface density (ΣSFR), (f) star formation efficiency (SFE), and (g) virial parameter (αvir).
