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

6. Miguel CerviñoLAEFF 27 Nov. 2006 Data Model --> semantics Define what its a synthesis model (unique definition):  Input Parameters: 1. Atmosphere models (from VOTable: SEDs, magnitudes...) Metallicity, resolution.... 2. Evolutionary tracks (from VOTable still without data model) Metallicity, age 3. Stellar birth-rate (IMF + SFH + Number stars formed) still without UCD  Outputs: 1. SED (VOTable) + model dispersion: Error model not implemented in VO 2. Tables of colors.... 3. Chemical evolution (still without UCD....)

7. Miguel CerviñoLAEFF 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.

8. Miguel CerviñoLAEFF 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. Miguel CerviñoLAEFF 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

11. Miguel CerviñoLAEFF 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. Miguel CerviñoLAEFF 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. Miguel CerviñoLAEFF 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.
