A transit observation at a central frequency of 165 MHz of PSR B0329+54 as it passes through the zenith above core station CS302. The antennas were combined coherently without further geometrical delay in order to point directly above. Left: the intensity of PSR B0329+54 as a function of time from transit and rotational phase. The variations are due to both the “fringe” pattern created by the coherent addition of the two HBA sub-stations of station CS302 and the wider single sub-station beam width. Right: the corresponding normalized S/N of the pulsar as a function of time from transit.
