At the observatory site, two standard PC perform all data acquisition and hardware control. Selection of observed frequencies and initiation of calibration measurements is performed fully autonomous according to predefined schedules. Every night, the daily data is transfered through the Internet from the observatory location to the Institute of Astronomy in Zurich. At the receiving site, the incoming data stream is searched for calibration data. If a full set of calibration measurements is available, the system parameters are re-determined.
Observational data is calibrated according to the latest determined system parameters.
For quicker localization of radio events, the data is compressed into overview spectrograms with reduced temporal and spectral resolution. This data is mainly used for quality control and system specification. In normal operation, the observational data is available on the following day.
