TAP, ADQL and PgSphere

[lesidaner-obs]

Hi

If PGSPHERE is a good program for image, for large catalog using 
Postgres, there is Q3C
It's a quad tree organization in postgres, we surely can find some body 
to talk about it, I have slides on it from Ivan Zolotukhin that will be 
present at interop.

See you in Garchen
