# ``Normal State'' Definitions

This section defines a terminology used to refer to ``normal states'' of the array afterwards.

- Single-Dish Continuum OK
  This means a continuum point source can be detected (in total power mode) with the one dish antenna. It implies that all the antenna control tasks work, that the pointing parameters are reasonably accurate for that antenna.
- Single-Dish OK
  This means a (standard) line source can be detected in ONOFF with one antenna. In addition to the previous state, it also implies that the receiver is tuned to the right frequency.
- Multi-Dish continuum OK
  This means a continuum point source can be detected (in total power mode) with the continuum dish detectors on all antennas. It implies the antenna control taks work for all antennas.
- Multi-Dish OK
  This means a (standard) line source can be detected on all antennas with the OBS ONOFF procedure. In addition to the previous state, it also implies that all receivers are tuned to the right frequency.

The last stage (which includes all the previous ones) is necessary for interferometry to work, but it may not be sufficient.
