AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroGrid Usability & Documentation Usability –Documentation –Infrastructure E.g. AstroScope front-end

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroGrid Usability –Web front page! –Workbench overall layout –Individual task support –Infrastructure –2 stream focussed support? Beginner/explorer – 1 st time user wizard/tutorial –AstroScope as typical front-end for archive work science workflow builder –Simple 2-step » need examples! –complex XML scripting capability »already have e.g. redshiftmaker

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroGrid Documentation See Templates (separate PDF from KTN also attached) JAT to coordinate astro input –Once per iteration Print existing wiki help pages and save as html as start point

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroScope Current Limitations Visualising very large numbers of returned records –By service Image (SIAP) Catalogue Spectra (SSAP) Spectral line data (SLAP) –Partly solved by clustering images around point? Obvious logging of returned resources –which services queried? –services alive with returned match(es)? –services alive but no match? –services not alive?

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University Save data locally or to MySpace –Issues with generated names and Myspace? –User naming of records Offset = bubble size/colour/boldness representations? –Prefer bubble size –reserve colours for common cat/image matches in missions? AstroScope Current Limitations

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroScope Future Aims – Front-end to Science Metadata! – identify relevant energy band info etc Cat entries from cone services - asterisks as only RA, DEC SIAP entries – use image title as label for node only? – request needed metadata where necessary from providers Link common image-to-catalogue entries directly – common colour? – but object may not be in both – image/catalogue entries may not be explicitly linked even within same mission archive

AstroGrid Usability & Docs, JBO, 6 th Dec 2005 Jonathan Tedds Leicester University AstroScope Future Aims – Front-end to Science Flux extraction from single source in image –In practice this will require detailed data processing of archived images for non-catalogued returned matches e.g. proposed LEDAS data centre project for X-ray astronomy –Cycle 3: enable extraction of flux where catalogued for returned match? Visualise linear offsets – use left pane of workbench –Intuitive to astronomers and missing in Datascope – user chooses mission from those returned in search via pull-down menu – AstroScope returns quoted positional errors for service selected – user selects bubble sizes for required offset ranges with slider
