Imaging
Station 1 2 N
Baseline
Baseline longer Resolution increased(VLBI: ~milliarcsec.)
# stations higher Improved calibration & imaging
Larger collecting area Increased sensitivity(In R.A. expressed as Aeff/Tsys )
Other aspects: •Frequency bandwidth (span, instant.)•Dynamic range (in image map)•RFI•Configuration, Site•Steaming Data, Computing power, Archiving•Network performance etc.
Many inderdependencies!
Configuration Resolution, imaging, brightness sensitivity etc.

Design Studies 1 to8
• Work has Clear objectives, Milestones and Deliverables to provide outcomes in measurable and verifiable form.
• DS1: Overall coordination and management. • DS2-6: Activity Cores, sub-divided into 21 coherent Design Study Tasks (DSx-Ty) • DS 7-8: “Synthesizing” the results from DS2-6
Structure optimized to continuously map the scientific requirements on the technical specifications to produce a common design goal SKADSUKJBOAvA171204
