Extended Data Fig. 10

The AGN names are shown on each panel. The mean count rates (exposures) (from top to bottom) are 30.5 (15.6 ks), 3.9 (14.3 ks) and 1.2 (33.3 ks) counts/s, respectively. These PDS were extracted exactly the same way as the average PDS of AT2018cow in Fig. 1. The location of AT2018cow’s QPO is indicated by the red shaded area. The errorbars represent the 1-σ uncertainties.
