Hide Zen home . ... Collecting more catalogues x2013; right now I would like to have catalogues like 2DF, RC3 . Allow the storage of SQL views in CAS. Arbitrary SQL queries from the user. My opinion is that's in the very future, since it requires the system to queue the queries, it requires the user quota system (of the user's data in the DB), and I guess it requires an additional (or more powerful) server. And right now we don't have any of these things x2026; . ... Zen, 2003-2007 ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ...
