  1. DS2 - Science & Data SimulationsMike Garrett (JIVE) SKADS Workshop 2006

  2. DS2 - Science & Data Simulations Context/Background: • DS2 ~ Major Activity within SKADS (1.4 MEuro EC funding) • Split into two separate but inter-related Tasks: • DS2-T1: Science Simulations (S. Rawlings, M. Jarvis - Oxford) • DS2-T2: Astronomical Data & Array Simulations (M. Garrett, C. Reynolds - JIVE) • Case developed in 2003 (JBO, Nancay, Madrid, Florence, Schiphol etc) • Proposal submitted early 2004; SKADS Project start July 2005 • DS2 start in spring 2006 SKADS Workshop 2006

  3. DS2 & SKADS Technical Programme Original goals of DS2 complimentary to SKADS Technical Developments: • EMBRACE (European Multi-beam Radio Astronomy Concept) - DS5 • Low-frequency bias in the original DS2 proposal and description of work European astronomers quick to recognise potential of Aperture Array: • “All sky” coverage, extremely wide-field of view • Frequency coverage (0.3 - 1.4 GHz) • Independently steerable, multiple fields-of-view (beams), experimental science…? • Transient buffer (data “replay”) capability • Instantaneous response to externally triggered events • Software telescope (clear upgrade path that follows Moore’s law) SKADS Workshop 2006

  4. DS2 - 2006 SKA Reference Design includes both Aperture Array & Smart Dishes: • SKADS DS2-T2 data simulation activity remains focused on EMBRACE Aperture Array, in comparison with other concepts (ATA, xNTD, KAT APERTIF etc) • Other more general goals include - Array Design/Configurations, Imaging & Calibration techniques • Other issues addressed: • Really Long baseline simulations, including Space VLBI (VSOP-2) • Precision Spacecraft Navigation (include. EMBRACE test obsns) • High frequency • Cylinders (BEST) • SKADS DS2-T1 provides input to DS2-T2 (e.g. sky models) but is quite general in its scope and well integrated with International SWG. SKADS Workshop 2006

  5. Summary • DS2 slow start, but catching up rapidly… (see Rawlings & Reynolds) • Focus remains on SKADS Aperture Array Technology for data simulations • Other studies (e.g. Science, Array Configurations, Imaging & Calibration techniques) are quite general. • Essential that both DS2-T1 and T2 are fully integrated into International SKA Programme. • Time to start thinking of how this effort continues within FP7 Preparatory Studies… .
