Search and Retrieve Chandra Data Products

The CDA has a variety of tools available for accessing Chandra data:


ChaSeR

A web-based application providing access to proprietary and public data. Search criteria must be entered individually, but ChaSeR provides the most detailed search results, including quick-look images, V&V reports, and links to processing status and publications tracked by the CDA operations group. Data packages are downloaded to an https staging area.

FTP
The primary and secondary data products of all public Chandra observations accessible from an HTTPS site
Chandra Fast Image
A simplified interface that allows the general public as well as professional astronomers quick access to images and event files
