Fig. 19


Footprint of an air shower measured with LOFAR. The signal strength (peak amplitude of the radio signal) is encoded logarithmically in the size of the marker and the color shows the time of arrival. The pentagons represent the positions of the particle detectors, their size is proportional to the number of recorded particles. The reconstructed shower axis is indicated by the blue cross for the core position and the line for the projected arrival direction.
