Two ALMAGAL fields showing different morphologies for similar 5σ emission areas. The blue contours in each field correspond to the 5σ noise level, while the yellow polygons represent the computed convex hull for the largest RoI in the fields. We have $Q_{5\sigma }^{\text{hull}}$ is ∼0.85 for the field in the top map, and ∼0.5 for the field in the bottom map. In both plots, the red ellipse in the bottom-right corner is the beam. Source AG name and running number as in Table 1.
