(last modified 10oct00)
The figures show the track across the dish that sources make at various
vs hour angle and za track vs hour angle (.ps) (.pdf):
Plot for declinations 0 through 18 degrees in 1 degree steps.
2-D plot of az,
za for declinations 0 through 38 (.ps) (.pdf):
degrees in 1 degree steps. Also plot hour angle in 5 minute steps. Note
