Top panel: distribution of the cluster radius measured from the average core positions for the sample of 514 ALMAGAL clumps with N_core ≥ 4 (in gray) and the subsample composed 347 clumps with d_cl ≥ 3.7 kpc (magenta). Bottom panel: clump heliocentric distance vs. measured cluster radius. The dashed line shows the physical size of the ALMAGAL FoV, while the dotted line indicates the area where the sensitivity is constant within a factor of two, i.e., angular sizes ∼13.5^′′. Cluster radii exceeding the FoV sizes are possible in systems with a substantial offset between the cluster and the image center.
