Dear all,

This is to let you know that, in the context of a collaborative framework between the Spanish virtual Observatory (SVO) and ESA-VO, we are developing a service to handle theoretical data (presently, stellar spectral data). The service uses VOSpec ( http://pma.standby.vilspa.esa.es:8080/vospec/index.html) as a plotting utility. There is already a prototype version of the system that will be presented in the Kyoto interop. during the Theory session.

The system works in a SSA-like way in a "two-steps" process: using the "format=metadata" option, the system returns a list of parameters that can be used for the query. Then, a proper consult can be done and the system returns a VOTable including a link to the data and that follows as close as possible the spectral data model.

In the near future we plan to implement a proper fitting tool between theoretical and observational SEDs. This will require passing the observed SED to the theoretical server.

On the other hand, we also plan to make a short presentation of PGos3, a collaboration between the Mexico-VO and SVO. PGos3 is a service that provides synthetic spectra, evolutionary tracks, isochrones and photoionization models. A preliminary version of the system can be found at: http://ov.inaoep.mx

Cheers,
