This brings up an interesting point. There is an azimuth and a weighted
azimuthal display. The azimuthal display comes out essentially
omnidirectional. The weighted display produces a heart shaped pattern
with the heart lobes to the NE/SW and a pretty deep null due north.
What weighting is used and why?
