Special Request Form

2004-12-02

There are a number of services provided by CXC-DS Operational groups that are not currently available through a web interface, but have required incidental e-mail. Requesting these services has now been consolidated though a single Request Form. It covers requests for old data versions, for special processing, for data on physical medium, for custom database queries, as well as anything not covered by these categories (or anywhere else). In addition, it allows us to track such requests.
