# Observing procedure

The procedure FLUX (corresponding to the project FLUX) is similar to BASE or POINT and runs under the OBS program. This procedure makes flux measurements in single-dish, multi-dish or interferometric mode. For commodity and a better calibration accuracy, it uses only the two following frequencies: SiOv1 at 86 GHz and 13CO(2-1) at 210 GHz. A third option allows using the current frequency tuning for only SMALL “holes” between two projects.
