Sky Server

[PhysicsGroupie]

Has anyone used the Sky Server (SDSS) for conducting astronomy experiments? I really like the facility, but I have a question of anybody who has used it. The data dictionary they publish is nice, but it is shy on details regarding the definition of each data element. For example, the sample 20 SQL queries provided to new users are straightforward in structure, but in terms of how the fields are used, more in-depth knowledge seems to be required.

 

Has anyone else figured out where to get more detailed scientific background info?

 

Thanks!
