# Array Operation

Since projects are typically spread over several months, the presence of visiting astronomers when their observations are scheduled is practically impossible. In the course of observations and data processing, four ``people'' will play a role: the `proposal PI (PI)`, i.e. any member of the team that proposed the observations, the `local contact`, the `on-duty astronomer`, i.e. an IRAM staff member present on the site, and the array `operator`. The `local contact` is an IRAM astronomer assigned to each project that does not have an in-house collaborator. His/her role is to help the `PI` in preparing the observations and in properly calibrating the data. In case of any problem, question, or doubt, the `PI` should contact his `local contact`. The `PI` can monitor the progress of his project on the web: `http://www.iram.fr/IRAMFR/PDB/ongoing-last.htmlhttp://www.iram.fr/IRAMFR/PDB/ongoing-last.html`; this page is updated three times per day. Note that checking results obtained in a given configuration, making intermediate data reductions, etc. is not the responsibility of the `local contact`. In certain cases, and upon request, remote login to a VISITORS account on the Grenoble computers can be granted to the `PI` to help him/her in this task.

The array is regularly operated by one `operator` and one `on-duty astronomer`. The `operator` has responsibility for conducting all observations, following pre-established observing procedures or under the supervision of the `on-duty astronomer` in case of unanticipated events. `Operators` have also full authority for all safety measures. Receiver tuning is done by the `operator`. The `on-duty astronomer` must assess the data quality during the observations by monitoring the array performance on standard calibrators. The `PI` usually will not be present on the site, but is expected to come to Grenoble for data calibration, once the project is finished.
