08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Project Overview (1) Access Atomic/Molecular DB starting with line lists Theoretical (measured or calculated) DB Observed line lists DB Necessary to access complementary information in order to interpret spectra or model astrophysical media: excitation rate coefficients, etc.. Clients: stronger evolution towards public software packages for spectral analysis and on line codes for astro. Simulation Shared, structured, complete and documented access to AM DB Standardisation O/I, queries, ressources ID

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Overview (2) Numerous DB are available Atomic lines: NIST DBs, Kurucz's CD-ROM, Atomic Line List of P. Van Hoof, TOPbase, Kelly Atomic Line DB, VALD, MCHF/MCDHF Collection, D.R.E.A.M, KAERI AMODS Molecular Lines: JPL Spectroscopic DB, CDMS, HITRAN, GEISA, NIST Other DB: IEAE, NIFS, CHIANTI, UMIST, BASECOL, small compilations Observed databases: ATOMDB, NIST,... Identification of Pbs Different DB have similar datasets DB have different levels of update Lengthy to identify origin of datasets, find all relevant description of data Useful data for a single astrophysical application are dispersed in various DB No homogeneous description of data

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Access to Lines: Data Model Based on fundamental physics, current databases and needs in astrophysics Current DM is centered around line for atom and molecules: electronic, vibrational, rotational transitions (couplings) Allows for identification of Chemical Species Level -->Quantum State-->Quantum numbers Origin and modification of Line Can be used to model other processes involving transitions because a line corresponds to a transition between two levels Could be extended to nuclear physics?

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Document status and perspectives Current version: 0.2 (26/9/2005) A discussion on several – albeit mostly minor – points is ongoing Short-term goal: Version agreed by mid-November - will be circulated to the DM group, as well as to atomic and molecular astrophysicists for comments Ultimate goal: achieve the status of a proposed recommendation by the next InterOp meeting

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Access : Query Parameters SLAP : Simple Line Access Protocol J. Salgado, P. Osuna, M. Guainazzi, I. Barbarisi, M.L. Dubernet Currently, version 0.1 By wavelength_min, _max, _mid By species: Fe I, H 2 0,... By type of levels (vibration, rotation,..) Combined with associated processes Would we allow search of other processes independently of lines? (next version?)

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Access to Lines: questions Registry parameters? Wavelength range Keywords = energies, atoms or molecules, processes Practically how should we proceed ? Some DB will implement VO, otherwise create VO providers Create Web Services and vizualization tools with filters

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Currently Implementing BASECOL database: excitation rate coefficients of molecules (rotation, vibration) Numerical data, documentation, references Web service VOTable output Errors (for various T and transitions) Tools for matching Basecol and CDMS/JPL spectroscopic database (necessary for carrying out science)

08/11/2005 M.L. Dubernet, Obernai - VO School - Introduction et BDD de Physique Summary Exchange standards for atomic & molecular standards Implementation for specific database Tools to handle existing data Registries Still not enough to carry out science Services are needed to complete data sets: using cheap approximations, extrapolations  next step for Basecol (only as a webservice)  should be provided for other processes
