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 (M_c), (b) effective radius (R_c), (c) surface density (﹩{{\rm{\Sigma }}}_{{{\rm{H}}}_{2}}﹩), (d) velocity dispersion (σ_c), (e) SFR surface density (Σ_SFR), (f) star formation efficiency (SFE), and (g) virial parameter (α_vir).
