Re: Comparison between observational and theoretical SEDs in VO.

Hi Enrique,

I'm intrigued by your announcement. The one thing I'd like to add is that since quite a while we, at the German Astrophysical Virtual Observatory, have been working on a tool that can be used for comparing observed with theoretical SEDs. The tool implements a statistical classifier and is available on our Web
(http://www.g-vo.org/portal/tile/products/services/sedclassifier/index.jsp). It is currently being used in a scientific project.

So far we have not incorporated any VOTable or VOSpec into our SED classifier, but are looking forward to doing so at some suitable point. May be we could join forces. Unfortunately, none of us will be participating in the Kyoto event, so we will have to look for another opportunity, in case you're interested. I myself am certainly open to discussions, also over the phone, at least to get started.

Cheers
Hans-Martin
