O3.2 Data Challenges and Strategies for Large Pulsar Projects

Ingrid Stairs (University of British Columbia)

Radio pulsar observations provide large data volumes which are handled in different ways depending on the scientific goals. Survey data typically have a few thousand frequency channels and sample rates of ten of microseconds; at present such data are processed offline, but in the future real-time processing will be required. Timing-mode observations for projects such as the search for a gravitational wave background are usually Nyquist-sampled and processed coherently, then integrated in frequency and time for long-term storage and further analysis. In both cases, data management is an increasingly complex problem; I will review some of the strategies currently used and planned to handle these data efficiently.
