This is a form-based service allowing users to run simple
queries against GAVO Data Center's ivoa.obscore table, with
some nods to users looking of data near the optical waveband.
For serious use, the `obscore table`_ should be queried through
TAP.
Note that queries without spatial constraints may take time out. You
probably ought to switch to async TAP if you really want to run such
queries.

The GAVO Data Center's sitewide SIAP version 2 service
publishes all the images published through the site. For more advanced
queries including uploads, all this data is also available through
ObsTAP.
