Attaching resources can also be done at the time a new Target is created. When clicking on the new Target, the Field Source , Spectral Spec , and the Observing Parameters panels contains a listing of the available resources that can be selected for the Target. Alternatively, the user can also choose to create and attach a new resource. In that case a new resource will be created in the corresponding Resources folder and attached to the Target.
After having attached a Field Source, Instrument Setup and one or more Observing Parameters, the Target information is complete. Clicking on the Target will show the complete Targetform in the Editors pane and highlights the parameters sets in the Resources folder that are attached to the selected Target. Similarly, by clicking on a resource, the Target to which this resource is attached will be highlighted. An example of this is visible in Figure 8.13 .
When selecting a Target, the form in the Editors pane displays the content of the attached FieldSource, SpectralSpec and Observing Parameters. At the top of each of the FieldSource, SpectralSpec and Observing Parameters forms, a line is displayed that gives the number of targets that use that parameter set. When it is used by more than one Target, a warning icon and the Edit Only This button appears along with the information. Editing a parameter set affects all the Targets to which it is attached. To only edit the parameter set for the Target which is displayed, click the Edit Only This button. This duplicates the parameter set and attaches it only to the Target which is being edited.
When selecting a FieldSource, SpectralSpec or Observing Parameters in the Resources folder, the form in the Editors pane provides information on how many targets are using it.
