Rectangle

This panel is only visible when ``1 Rectangular Field'' is selected in the Source panel. A recent change to the OT is that it is now possible to define multiple sources, each of which uses a rectangular field pattern. To do this, one must start with only a single source in the Science Goal. This can be set up as a rectangular mosaic and any further sources that are defined will be forced to use rectangular field patterns.

For each rectangle, the OT will calculate a mosaic pattern for the 12- and 7-m arrays based on the spacing parameter. A larger version of the user-drawn rectangle will be used for raster scanning with the TP array. A total of 150 12-m array pointings is allowed, summed over all rectangles.

The number of pointings calculated by the OT is displayed, for the 12-m and (if required based on the Control & Performance parameters) 7-m arrays. A button is provided to export the pointings (12-m and 7-m array) to an ASCII file on disk.
