AstroGrid Science Advisory Groupwiki keyword: AGSAG

Meets every six months Inputs science priorities into the AstroGrid 'science'

iterations

Sep 2003 meeting: Defined key priorities for Itn 04

Large scale redshift determinations for imaging data sets Set priorities on key data and tools

Feb 2004 meeting: Key priorities for Int 06

Solar case: coronal waves > key data sets and tools Extension to extragalactic cases

Future aim: encourage use to 'do' science

<18-Feb-2004> AstroGrid Science @ GSC : MRC 4

Meeting the Requirements in Itn04

SAG priorities for Itn04: Access to imaging data Access to basic tool set : image extraction

Itn04 delivered: WFS/2MASS/6dF/USNOB data available through AstroGrid Access to large catalogue sets through ViZier Access to basic tools: Sextractor, Data Federation, hyperz

Added value via access to AVO demo tool Access to multi-λ 'GOODS' data Access to extra VO tools

VOPlot, SED tool

Itn06: Solar Focuswiki keyword: Intn06SoloarCoronalWaves

Key long term solar/STP priority related to Space WeatherItn06 focus: solar coronal waves Provision of AstroGrid service to enable feature

visualisation User selected data: all disk image > SOHO-EIT Automate relevant data collection for feature: TRACE, Yohkoh Data registration Movie generation

Service-reuse Theory Image stacks

<18-Feb-2004> AstroGrid Science @ GSC : MRC 9

Itn06: Extragalactic Astronomy Services

Key extragalactic issue: Distance For deep imaging/ sepectral survey's Provide 'one-stop shop' distance service

Provision of multiple distance estimators Access to spectral distances: PCM analysis of spectra Access to photometric methods

SED matching: hyperz Baysian methods: bpz Neural network methods; ANNz

Service locates data, runs methods Output: multiple distance estimates

AstroGrid Beta Testing:wiki keyword: BetaTesting

Programme begun Q4 2003 with Itn 03 testingBeta testing continues with Iteration 04 product Programme includes access to AVO tools (e.g. Jan 2004

demo)

Beta tester pool (currently ~30) composes: Science Advisory Group eScience astronomy students Interested astronomers

Beta tester programme providing feedback Usability > input to GUI design Functionality > informs access to data and tools Reliability > uptime, speed of response, bugs

AstroGrid and the GGFhttp://forge.gridforum.org/projects/astro-rg

AstroGrid initiative to connect astronomy requiremtns and 'grid' computingAstro-RG GGF research group initiated Co-chairs Walton (AstroGrid) and Reagan (NVO)

Aim to feed astronomical (science) requirements to GGF Inform computing requirements by usage reports 'gap' analysis needs/functionality

Towards AstroGrid2

AstroGrid remains on target to deliver against key science milestones

Mass scale access to WFCAM IR survey data (prep for VISTA) Access to european and world data > through IVOA stds 'Level 1' data mining > image extraction and visualisation

Science priority for AstroGrid2 Ensure wide science take up of a robust system Encourage user demand for resource (disks etc) through AG

'Seed' provision of better tools Encourages external provision of capabilities Maximise exploitation of seamless data access/discovery
