Extended Data Fig. 6: Dynamic spectrum, ACF and PS for burst B4 from FRB 20200120E.
From: Burst timescales and luminosities as links between young pulsars and fast radio bursts

Note the average ACF shows two temporal scales (unlike the 3 seen for burst B3). Additionally, we only plot the red noise power law plus white noise model since any wide Lorentzian features are less apparent in this power spectrum, than the case of B3.
