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. |
Analysis GuidesSince the number of CIAO Science Threads is always increasing, there is a great demand for a roadmap on how to apply them to the data. The Analysis Guides presented here were written for that purpose. Each guide takes a certain instrument configuration (ACIS, for example) or type of analysis (e.g., extended sources) and lists the relevant threads. Along with the listing is a brief explanation of the purpose of each task. The goal is to help the user complete the analysis without requiring that every thread be read.
