Total intensity of the wavefields in the two observations (with the wavefield intensities of the 19 subbands aligned using ﹩(\tau ,\dot{\tau })﹩ coordinates before summing). The color scale corresponds to ﹩{\mathrm{log}}_{10}| W(\tau ,\dot{\tau }){| }^{2}﹩ in arbitrary units. A plus sign denotes the measured center of the 2.4 ms feature in both panels. The excess noise around τ = 0, 1.6, and 3.2 ms (as well as, more faintly, at 0.8 and 2.4 ms) is due to the regular pulse emission. An interactive version of this figure, which shows the ﹩(\tau ,\dot{\tau })﹩ wavefields for each frequency band, is available on the Journal website.
