Azimuth Topology

The 30m antenna has azimuth limits of 60 and 460 degrees. Azimuth 360 degrees is due North. Therefore there is an overlap range approximately toward East-Northeast, which the antenna can reach at a low azimuth 60 to 100 (from the South) or at a high azimuth 420 to 460 (from the North).

`SET TOPOLOGY LOW` selects to use the azimuth range 60 to 420 degrees.

`SET TOPOLOGY HIGH` selects to use the azimuth range 100 to 460 degrees.

Note that `SET TOPOLOGY` only has an effect for sources with an azimuth in the overlap range; when a source is in the azimuth range 100 to 420 degrees `SET TOPOLOGY` does not matter.

Compare Figure 4.

Figure 4: Azimuth Topology. The left side shows in blue the range for `SET TOPOLOGY LOW`, the right side shows in red the range for `SET TOPOLOGY HIGH`. (Compare Section 6.2; figure prepared by Joaquín Santiago)
