Extended Data Fig. 1: Autocorrelation functions (ACFs) and power spectra for B4-sb1 and B3.
From: Highly polarized microstructure from the repeating FRB 20180916B
The temporal profiles of bursts B4-sb1 (top frame) and B3 (bottom frame) are shown in the top left of each frame (panels a and e). The corresponding ACF of these temporal profiles are shown in panels b and f. The corresponding power spectra of the temporal profiles are shown in panels c and g, and the orange line is the power spectrum downsampled in frequency by a factor of 3. Overplotted in pink on the power spectrum is the best fit power law plus white noise component. Panels d and h are the residuals (2 × power spectrum/best fit model).
