These three goals have a common structure. Each contains:
-
A target list
-
A calibrator list
-
A spectral setup
Each source in the target list and calibrator list will be observed using the one spectral setup specified here. The target list and calibrator list are edited using the target list and calibrator editors, described below, while the spectral setup is edited using the same spectral setup editor as used throughout the OT. When the target list, calibrator list and spectral setup are to your satisfaction, SBs can automatically generated from the goal by right-clicking on the goal in the project tree and selecting Generate SBs from the selected goal, just as when generating SBs from a Science Goal. The current SB generation strategy is to:
-
Generate two observing groups: Observing Group 1, for initial calibrators, and Observing Group 2, for goal targets and repeated calibrations.
-
Create a virtual target for each calibrator in the calibrator list, apart from the phase calibrator. Each of these calibration Targets is added to Observing Group 1, and will be observed in an initial calibration pass when the project is executed.
-
If a phase calibrator is specified, create a phase calibrator virtual Target and add it to Observing Group 2. This phase calibration target will be observed at regular intervals throughout the project. The specifics of how frequently it will be observed can be changed by editing the PhaseCalParameters, which can be found as a leaf node of the generated SB in the project tree.
-
A target will be created in Observing Group 2 for each calibrator in the predefined target list, or alternatively one virtual target containing the user's search criteria will be created if the list is to be generated at project execution time.
Below the Target List and Survey Calibrators form are discussed. The form for the Spectral Setup is identical to the form for a Science Goal (see Section
6.3.3
