4  Observing modes

A couple of standard observing modes are available for the LWA1, basically limited by the backends available.

4.1  Interferometric modes

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:

• DRX Tracking RA/DEC
• DRX Tracking Jupiter (UNTESTED AT THIS STAGE, USE RA/DEC)
• DRX Tracking Solar (UNTESTED AT THIS STAGE, USE RA/DEC)
• DRX Stepped (NOT AVAILABLE AT THIS STAGE)
• TBW
• TBN

4.2  Transient mode

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).
