• Part II: 2nd half of SKADS 2007-2009– closer ties with technology development

– especially costing

– what science relies entirely on mid freq A-A technology ?

SKADS Science SimulationsSKADS Science Simulations

• Pure sky simulations should now feed back into telescope simulations, configuration studies, and costing

• Thank you for commenting on technical requirements– Field of view (mapping speed)

– Total Frequency range

– Instantaneous bandwidth

– Spectral resolution

– Angular resolution

– Sensitivity (Aeff/Tsys)

Pushchino ProceedingsPushchino Proceedings

• This is an important summary of simulations

• Sky simulations with a realistic SKA design in mind

• Please send text and images by 31 August– Text format: TeX preferred, doc, or whatever,…

– Images: ps, eps, bmp, …

– Upload to wiki: http://webmail.jb.man.ac.uk/skadswiki/PushchinoMeeting

– Email me if you have trouble: Steve.Torchinsky@obspm.fr

Pushchino 2007 Jul 30-Aug 1 Steve TorchinskyPushchino Conclusions

The next two yearsThe next two years

• Firm-up simulations

• continue telescope and configuration studies– Communicate results to sky simulators, and to the design and

costing team

– eg. Configuration studies and trenching costs

• concentrate sky simulations on benchmark capabilities

• Lobby for capabilities if it’s important– eg. pulsars: core collecting area

• Publications !
