The dynamic spectra showing the relative signal intensity as a function of time and frequency for an observation of Cygnus A made by the LOFAR remote stations across the Netherlands on 14th July 2018 between 17:00 UT and 18:00 UT. The 24 closely spaced stations comprising the LOFAR core, some with separations as small as ~100 m, are labelled as ‘Core’ and the dynamic spectrum for CS002 is shown. To enhance the clarity of this figure, both the intensity scale and time axes differ from Figure 1 and the prefix RS is removed from selected stations. The relative signal intensity is shown on a scale between 0 and 2, with white representing a relative signal intensity of 1.0 and the duration of the time axis is one hour.
