The basic interferometric mode is used when the data is passed through the digital receiver with individual tunings of each beam. In this mode the following observing modes are available:
The transient mode is suitable for all-sky imaging and monitoring, and for diagnostics of the system. The ASI backend available in 2012 will be the PASI (Sect. 3.1).
