Data Caveats

This page contains warnings concerning the quality of data products in the Chandra Archive, grouped by instrument. For a more detailed description of the data products, visit the Data Products Guide.

CIAO is designed for use with data with a processing version of "R4CU5UPD8" or "DS6.0.0" or higher; see the Note on Processing Versions for more information. To obtain the most up-to-date processing for a given observation, visit the Chandra Data Archive.

All data received from the Chandra X-ray Observatory is processed through the standard data processing (SDP) pipelines at the Chandra X-ray Center. For each revision to the SDP, the release notes address the changes in the pipeline that may affect data products available to observers.

If you have any specific questions about your data, please email the Helpdesk.
