The Seismic Plus Portal E. Michel, C. Renié, K. Belkacem,M. Abed/ SPACEINN-WP3-meeting-1 21-22/10/2013 Observatoire de Paris Motivations & Objectives • A large number of seismic data sources (stellar and solar) now available (CoRoT, Kepler, SDO, etc...) • Complementary data also necessary and numerous (spectroscopy, interferometry, etc...) Issue: data bases are scattered and inhomogeneous ✓ Difficult to fully exploit, need for visibility ✓ Hinders a broad community use of seismic data Major objectives of the Portal: ✓ Coordinated access to the large variety of data sources available ✓ Provide tools to handle and combine data for a broad scientific community Motivations & Objectives The Seismic Plus is intended to gather in a same well identified place: • Homogeneous description of the data available from various sources: - sources of seismic data (space or ground-based) for stars and the Sun - sources of complementary data (space or ground-based) commonly used in complement to seismic data to lead interpretational studies (e.g. fund parameters, astrometric & spectroscopic sources, models & numerical simulation sources…) • Tools to access and combine data from these different sources and possibly produce new outputs The Portal overall architecture Three different levels have been defined (L0,L1,L2) L0: Standard description of the data sources L1: Where-is-what? (WIW) L2: Data Access & Handling Access to databases Data Handling (tools) The Portal overall architecture – L0 L0: Description of the data sources and tools available at the Portal • This level is intended to provide us with a standard and homogeneous description of available databases and tools available at the Portal - L0.0 : a ‘multi-approach’ presentation Considering the potentially large number of sources, presentation according to keywords… • For each data source, two sub-levels of description are considered: - L0.1 : Some general text explaining the main content of the database (following a standard scheme tbd) e.g.: The GAUDI database provides access to high resolution spectra collected between XX/XX/XX and XX/XX/XX, in the framework of the COROT GroundBased Seismology Programme, it contains ... The Portal overall architecture – L0 L0: Description of the data sources and tools available at the Portal - L0.1.1 : Field descriptions e.g.: description of the fields as a table needs some VO stuff screen shot of the field description of KEPLER KOI (http://archive.stsci.edu/search_fields.php?mission=keple r_koi) L0 - Census of data sources: CoRoT archive -- KASOC archive / Kepler archive -- Ground-based ✓Time series: CoRoT complementary archive -- SOHO -- SOHO/VIRGO/PMO6V -SOHO/VIRGO/DIARAD -- SOHO/VIRGOS/SPM –SOHO/GolfSOHO/MDI -SOHO/…LASCO,CELIAS/MTOF/PM/CTOF/STOF/HSTOF/SEM…? -SDO -- SDO/HMI -- SDO/AIA ? -- SDO/… -- GONG -- Bison -- MARK-I PASTEL -- APOGEE -- P2F -- Hipparcos&Tycho ✓Fundamental parameters: catalogue –(GAIA) -- SSI Stellar Seismic (Teff, Fe/H, L,pi,…) Indices APOGEE (Sloan Digital Survey) -- GAUDI -✓Spectra: Gaia ESO Survey (GES) -- TBL Legacy -(observed & theoretical): POLLUX ✓Stellar models: (Teff, Fe/H, L,pi,…) Stellar and solar models and oscillation parameters • In blue, database within the SPACEINN project • CF list circulated for inquiry within SpaceInn consortium (aug. 2013) L0 - Census of tools available in the Portal: • Tools will appear at different levels of the portal • They will be whether implemented in the portal or an access will be provided for already existing tools Examples : - Tools to be implemented: a broad community will be interested in accessing seismic estimates of masses, radii for a large number of stars SSI (seismic indices) Database of groundbased obs (Teff) Tool = scaling relations Output = seismic masses, radii L0 - Census of tools available in the Portal: Examples : - Already existing tools: visualize specific data to evaluate their interest (look at a spectrum, an image, a time series…) One can use already existing tools such as TOPCAT (Tool for OPerations on Catalogues And Tables, http://www.star.bris.ac.uk/~mbt/topcat/) The portal will use/give access to this tool - no implementation needed The Portal overall architecture – L1 L1: Where-Is-What? (WIW) For a given request (e.g., a list of stars), it provides (at least): The Gaudi data base provides access to high resolution spectra collected from XX/… - list of sources where data exist, - Access to description of the source content star Source 1 Star 1 X Star 2 X … Star n Source 2 … Source n X X X X … … … X X Possible types of requests – L1 ✓For stars: • List of stars (use of a cross-identifyer, CDS) • Selection by coordinates + magnitude range • Type of star (main-sequence / red-giant / etc...) • Type of variable star (solar-like pulsator / delta-scuti / etc...) • Other? ✓For the Sun: ✓For stars & the Sun: • period(s) of time •remarquable events(high activity,…) • Obs technique/Spectral domain ? • Coordinates (for resolved observation of the Sun) • Other? • Data type (e.g. time series / spectro / imagery / etc...) • Other? The Portal overall architecture – L2 L2: Data access & Handling Data Access from selected sources to : • Visualize specific data to evaluate their interest (look at a spectrum, an image, a time series…) • Download them on his personal computer to exploit them (according to a list, a selection by position or magnitude…) Quick look image: light-curve, spectrum,… if exist Download data from source n Download data for star n star Source 1 Star 1 X Star 2 X … Star n Source 2 … Source n X X … … … X X X X X X X The Portal overall architecture – L2 L2: Data access & Handling Data Handling : • Use tools made available at the portal to produce new output data from the combination or analysis of input data New output TOOL n star Source 1 Star 1 X Star 2 X … Star n Source 2 … Source n X X … … … X X X X X X X The Portal – technical options Portal / Data source interface The Seismic Plus portal Query VOTable XML ? Data Access Layer service Data archive Data description Data access Tools VO standard, protocol and format : TAP : Table Access Protocol SSA : Simple Spectra Access … Specific to data archive The Portal – technical options VO standard, protocol and format For example Table Access Protocol (TAP) Defines Web service protocol for accessing general table data: Data queries for data access Metadata queries for data description Testing DaCHS framework (TAP implementation developped by the German VO) with SSI database. Visibility in VO registries and VO tools like TOPCAT, VOSPEC Help to define a common language, vocabulary Make portal developments and maintenance easier Knowledge and support from OV-Paris Location near the database The Portal – Planning & needs Manpower : • PI: Eric Michel (Kevin Belkacem) • Project Manager: Christian Renié • VO expertise: OVPARIS/Pierre Le Sidaner • Portal develop.: Mahfoudh Abed (CDD SpaceInn) Planning : -deliverable D3.1, month 12: Set of data access and tools to be implemented The Portal – Planning & needs Deliverables : Planning : • (First) list of data sources and tools -> december 2013 • Need to have balanced (ambitious/reasonable) lists • Need efficient feed-back from data sources managers: YOU + others • Portal Opening (< month 30)
