The Seismic Plus Portal

E. Michel, C. Renié, K. Belkacem,M. Abed/ SPACEINN-WP3-meeting-1 21-22/10/2013 Observatoire de Paris


The seismic plus portal

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


The seismic plus portal

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 seismic plus portal

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 seismic plus portal

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 Ground-Based Seismology Programme, it contains ...

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

The seismic plus portal

L0 - Census of data sources:

  • Time series:

CoRoT archive -- KASOC archive / Kepler archive -- Ground-based CoRoT complementary archive -- SOHO -- SOHO/VIRGO/PMO6V -- SOHO/VIRGO/DIARAD -- SOHO/VIRGOS/SPM –SOHO/Golf-SOHO/MDI -- SOHO/…LASCO,CELIAS/MTOF/PM/CTOF/STOF/HSTOF/SEM…? -- SDO -- SDO/HMI -- SDO/AIA ? -- SDO/… -- GONG -- Bison -- MARK-I

  • Fundamental parameters:(Teff, Fe/H, L,pi,…)

PASTEL -- APOGEE -- P2F -- Hipparcos&Tycho catalogue –(GAIA) -- SSI Stellar Seismic Indices

  • Spectra: (observed & theoretical):

APOGEE (Sloan Digital Survey) -- GAUDI -- Gaia ESO Survey (GES) -- TBL Legacy -- 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)


The seismic plus portal

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)

Output

=

seismic masses, radii

Tool

=

scaling relations

Database of ground-based obs (Teff)


The seismic plus portal

L0 - Census of tools available in the Portal:

Examples :

visualize specific data to evaluate their interest (look at a spectrum, an image, a time series…)

- Already existing tools:

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 seismic plus portal

The Portal overall architecture – L1

L1:Where-Is-What? (WIW)

For a given request (e.g., a list of stars), it provides (at least):

- list of sources where data exist,

- Access to description of the source content

The Gaudi data base providesaccess to high resolutionspectracollectedfrom XX/…


The seismic plus portal

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:

  • period(s) of time

  • remarquable events(high activity,…)

  • Obs technique/Spectral domain ?

  • Coordinates (for resolved observation of the Sun)

  • Other?

  • For stars & the Sun:

  • Data type (e.g. time series / spectro / imagery / etc...)

  • Other?


The seismic plus portal

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

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

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 seismic plus portal

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)
