Stacked amplitude spectrum of all δ Scuti pulsators in this study. Clusters are ordered by age (youngest on top). The red dotted lines separate each cluster. Within each cluster, stars are sorted by Teff, with the coolest on top. Note the appearance of δ Scuti stars with regular pulsation patterns in the younger (≲200 Myr) open clusters.
