Release of anonymous ftp version of the CDA

2002-09-19

The primary (only!) products of all public Chandra observations are now accessible on an anonymous ftp site, cdaftp. This archive is being kept up-to-date in real time. That means that observations that are released to the public are available from this ftp archive almost immediately and that old data versions are replaced by new, reprocessed ones as soon as they are released.
Note that, although it provides access to these data products by ObsId, there are no search and query facilities. For search engines and more sophisticated retrieve options we strongly recommend the use of ChaSeR or WebChaSeR.

See the README file for details.
