Spectral Line

Four panels for the four basebands will be visible and one spectral window can be added to each. Adding a spectral window is done either by selecting spectral lines from the spectral line catalogue or by adding them manually. One of the spectral windows should be selected as that which will set the Representative Frequency. This defaults to the centre of the spectral window, but can be changed at the bottom of the page. This sets the size of the antenna beams drawn in the Visual Spatial Editor and is also used to work out the time estimate for the Science Goal.

The spectral window table has the following columns. Most accept input by being double-clicked.
