Observations

The PI must specify all aspects of his/her program in an observing procedure. Standard observations can be made using general, parametric procedures. An example is given in Sect..

The operator will execute the observing procedure, and the on-duty astronomer will monitor the data quality by examining the observations of phase calibration sources. In the case of peculiar observing conditions (high or exceptionally low phase drifts, calibrators too weak, etc.), the on-duty astronomer has full authority to modify the parameters of the observing procedures. He/She will, of course, try to consult with the PI or local contact.

Non-standard observations may require a specific arrangement with the local contact or on-duty astronomer, or may even require an in-house collaborator.
