Matching CIAO and CALDB VersionsCIAO 3.4 requires CALDB 3.3.0 or higher to operate properly. CALDB 3.4.0 and higher should not be used unless you are running CIAO 3.4 or CIAO 4.0. Are your versions mismatched? Time to update CIAO and CALDB!
11 Nov 2008 These are the webpages relative to the CIAO 3.4 release (18 December 2006). They are no longer actively updated, however the CXC will continue limited support of CIAO 3.4 for the near future. CIAO 3.4 users should check the CALDB 3 website for compatible calibration updates. 15 Dec 2008 The newest version of the Chandra Interactive Analysis of Observations software, is CIAO 4.1, released on 15 December 2008. Read the release notes for detailed information. This release requires that CALDB 4.1.0 be installed for the software to work correctly. |
Data Products GuideThe Data Products Guide describes the contents and purpose of each Chandra data product. Detailed information is available for each of the following filetypes: These pages may also be accessed from the tables of data products. This document is a work in progress. For the most up-to-date description of the common Chandra data products, refer to the Introduction to the Data Products thread. Primary ProductsIn March 2002, the data products were rearranged such that all products necessary for most analyses are in the primary directory.
Secondary ProductsIf you are interested in reprocessing your data, you will also need the level 1 files, which are in the secondary directory.
Supporting ProductsThe pipeline-produced supporting products are generally not needed in data analysis. These files are created by intermediate processing steps.
