## Producing setups

Once the LINE, NARROW, and SPECTRAL commands have been used to define the tuning of the receiver and backend, the command PRINT filename allows one to write in an output file the corresponding OBS commands. This file can directly be included in the observing procedure (“setup” file) to be run at the Plateau de Bure.
