Hi
We, at the Spanish VO, would like to introduce you to VOSA
(VO Sed Analyzer), a web application developed using VO
resources to fit observational data with theoretical models
and, so, infer physical properties for the observed objects.
We actually intend to give a short presentation at Baltimore
about it.
In summary, it resolves objects using the VO, retrieves photometry from VO
catalogues, allows the user to upload his/her own photometry too, uses
theoretical stellar models from the VO to fit the observed data and find values
for the effective temperature, gravity and metallicity, and then uses
theoretical isochrones and evolutionary tracks from VO servers to estimate
values for the mass and age of the objects.
The application is available at: http://svo.laeff.inta.es/theory/vosa
and a paper by Bayo et al, presenting it and using it for the C69 cluster is
already accepted for publication in Astronomy and Astrophysics.
If you find it interesting, we invite you to try it and,
please, send us any comment about it.
