## Setup Procedure

The standard setup defines the target source(s), configures the spectral correlator, selects the observing frequency, and leaves the system ready for receiver tuning.

All information appearing on lines marked `!**!` must have been supplied in the observing proposal, lines marked `!* !` will use default values if not specified. The remaining part of the procedure will be defined by IRAM personal (your `local contact`, usually). The project number (zzzzzzzz in this example) is assigned by IRAM when observing proposals are received. After final checking by IRAM staff, this file will be given to the `operators` and `Astronomers on Duty`, together with a copy of the proposal and any accompanying information the `PI` may find useful. The `on-duty astronomer` will fill in a `NOTE file` that summarizes the individual conditions and particular problems encountered during each track observed. The `NOTE file` will provide some suggestions in cases where the data calibration is not straight-forward. A copy of it will be given to the `PI` when he/she visits Grenoble for data reduction after the project is completed.
