Single Pointings

Multiple instances of single pointings can be added to the field definition by using the "Add a FOV" button on the toolbar and then clicking at the position in the image where the antenna should point - this must be clicked every time a pointing is to be added. For your convenience, a single pointing is created by default at zero offset from the source coordinates. Once defined, pointings can be moved using the mouse or deleted. Clicking on a pointing will cause its background to become opaque - this indicates that this pointing has been selected and can, for example, be deleted using the scissors icon in the toolbar or moved by being dragged with the mouse. More than one pointing can be selected at any one time, either by using the rectangular selection button in the toolbar, or by holding down the Ctrl key whilst clicking on each pointing in turn. A subsequent dragging or delete operation will then apply to all pointings.

The pointings defined in the Spatial Editor are displayed in the Forms Editor where they can be edited or deleted.
