Tracking the processing status of Chandra observations

摘要

The Chandra Data Archive has been archiving and distributing data for the Chandra X-ray Observatory and keeping observers informed of the status of their observations since shortly after launch in July 1999. Due to the complicated processing history of Chandra data, it became apparent that a database was needed to track this history on an observation by observation basis. The result is the Processing Status Database and the Chandra Observations Processing Status tool. In this paper, a description of the database design is given, followed by details of the tools which populate and display the database.
