Whisker plots showing the distribution of the two measured estimates of the cluster elongation for the different classes of ALMAGAL clumps identified by the number of cores inside the CH polygon: sparse, where no further core lies inside it; intermediate, where there are fewer cores than the ones defining the polygon itself; clustered, where there are more cores than the ones at polygon vertices. The left panel presents the elongation e_CH, defined as the ratio of the major to the minor axis of the best fitting ellipse to the CH polygon, while the right panel refers to the ratio ξ of the circular area of the cluster to the area of the CH polygon. The first and third quartiles, and the 10th and 90th percentiles of the distribution are indicated by the boxes and the segment extremes, respectively, while the central segment corresponds to the median.
