Extended Data Fig. 7: Dynamic spectrum of the 19:12:33 20 July 2022 pulse detected with the APSUSE instrument on MeerKAT.
From: A long-period radio transient active for three decades

The time resolution is 3.9 ms and the frequency resolution is 8.5 MHz. Strong interference signals have been removed in the 950-MHz band and at the band edges below 577 MHz and above 1,065 MHz. The data are shown before de-dispersion (a) and after de-dispersion (b).
