  1. Modelos de síntesis, modelos de atmósferas e isocronas en el VO Miguel Cerviño (IAA-CSIC/SVO) + LAEFF-INTA/SVO +INAOE VO/MVO LAEFF 27 Nov. 2006

  2. LAEFF 27 Nov. 2006 Databases, Interoperability and Science Analysis tools & Science Observed data Theoretical data Observational data bases, OK But: 1.- Where are databases of theoretical models? 2.- How to describe a theoretical model?

  3. LAEFF 27 Nov. 2006 Working groups http://www.ivoa.net ---> Community

  4. LAEFF 27 Nov. 2006 Synthesis models in the VO context + (http://ov.inaoep.mx)

  5. LAEFF 27 Nov. 2006 Synthesis models in the VO context (http://ov.inaoep.mx)

  6. LAEFF 27 Nov. 2006 Data Model --> semantics • Define what its a synthesis model (unique definition): • Input Parameters: • Atmosphere models (from VOTable: SEDs, magnitudes...) • Metallicity, resolution .... • Evolutionary tracks (from VOTable still without data model) • Metallicity, age • Stellar birth-rate (IMF + SFH + Number stars formed) still without UCD • Outputs: • SED (VOTable) + model dispersion: Error model not implemented in VO • Tables of colors.... • Chemical evolution (still without UCD....)

  7. LAEFF 27 Nov. 2006 Data Access Layer -->Applications • Define the parameter domain of models: • Observational Data: COOSYS, • a simple search can be done: Name, RA, DEC • In theoretical data the parameter space is not know a priori • TSAP (theoretical spectral access protocol) --> Theory WG • 1st query: What is the paremeter space; RESULT: VOTable that can be transformed in a from. http://localhost/script?format=metadata • 2nd query: What region of the parameter space you want? VOTable with catalog of VOTables! http://localhost/script?par1_max=...+parn_min=... • 3rd query: What is the individual model you want? VOTable with specific data Only few applications can use TSAP (VOSpec) It is needed generalize TSAP and/or build JAVA tools for metadata access Teoria en el VO C. Rodrigo et al.SVO meeting Abril 2006 www.laeff.esa.es/Laeff/svo/meeting0604/crodrigo.ppt

  8. LAEFF 27 Nov. 2006 Summary (I) • Synthesis models in the VO means • Atmosphere catalogs • Tracks/Isochrone catalogs • Synthesis model repository? Or on-the-fly models? • TSAP developement • Applications including TSAP • UCD+DataModel of theoretical data

  9. LAEFF 27 Nov. 2006 Access to models VOSpec http://esavo.esa.int/vospec/ • PEGASE server using TSAP • PGos3 server using TSAP Grupo de ciencia de observatorios virtuales del INAOE • http://ov.inaoep.mx • PGos3 (http://ov.inaoep.mx/pgos3/) • INAOE, IA-UNAM, IAA/SVO LAEFF/SVO (Spain) CEA applications - AstroGrid

  10. LAEFF 27 Nov. 2006 VOSpec • Web.... M. Guinazzi et al.IAU Praga 2006

  11. LAEFF 27 Nov. 2006 PGos3 (p.i. Elena Terlevich & Miguel Cerviño) • What is PGos3? • Cooperative tool • Repository of theoretical SSPs • same format (Votables) • Same tools • “democratic” choices (sb99, pegase, sed@....) • Why? • Fitting (IA, standard chi-2 fit, grid...) • Analisys Cathedral: (P.I.: Roberto Terlevich, Aurelio López)

  12. LAEFF 27 Nov. 2006 PGos3 current/future jobs ... • StarLight analisys... (www + pdf) • Analisys of VO data! • Colors? (spectra VOTable + Filter VOTable) • Rebbinig?... • Test for Theoretical access protocols in IVOA • “Small” applications for IVOA

  13. LAEFF 27 Nov. 2006 Conclusions  Several servers ready • Data models can be obtained for SEDs only • There is no data model for tables with other pourposes: t-colors, isocrhones, chemical evolution.... Data models are science!  General access protocol needed ( Carlos Rodrigo ;)  Error treatment  Inclusion of SSP models (including probabilistic distributions) e.j.
