Extended Data Fig. 1: Radio signal from FRBs 20210206A and 20210213A.

From: Sub-second periodicity in a fast radio burst

Extended Data Fig. 1

a,b, Waterfall plots of the signal intensity (colour-coded) as a function of time and frequency. Frequency channels missing or masked owing to radio-frequency interference are replaced with off-burst median values and are indicated in red. Effects of dispersion have been removed and data have been plotted at the native frequency resolution of 390.625 kHz and at time resolutions of 0.16 and 0.32 ms, respectively. c,d, In black, the pulse profiles obtained by averaging the frequency channels of the waterfall plots in which signal is visible. Peak locations are highlighted by vertical lines. a,c, FRB 20210206A. b,d, FRB 20210213A.
