Relation between the column densities of the iCOMs derived from the rotational diagrams at GMC scales (θ = 1.6″; left-hand side of the figure) and at pSSC scales (θ = 0.12″; right-hand side of the figure), for each region (GMC 7: blue; GMC 6: green; pSSC 5: magenta; pSSC 2: orange). Pearson's coefficient and p-values are indicated in the bottom right part of each plot. Dashed and full grey lines indicate abundance ratio factors. Panel k is highlighted as the correlation between CH₂NH and C₂H₅OH is the same at both GMC-scale and pSSC-scale. For reference for the location of each region, we added a map of the CH₂NH (4_1,3−3_1,2) transition in the bottom-left part of the figure.
