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. |
Downloading CIAO 3.4Latest CIAO Update: 29 January 2007 (OS X platforms only) CIAO 3.4 is available for:
The Platform Support page has more information on the officially supported CIAO platforms. To use CIAO you also need to have the Calibration Database (CALDB) installed on your system: CALDB 3.3.0 or higher is required for the proper operation of CIAO 3.4. Likewise, do not update to CALDB 3.5.0 unless you are using CIAO 3.4. Some tool changes and calibration released in CIAO 3.4 and CALDB 3.3.0 affect analyses in progress, i.e. certain processing steps should be run again for greater accuracy. Browser IssuesThere are known problems with the CIAO download pages in Internet Explorer on the Mac OS X platform. We recommend that you choose an alternate browser - such as Safari (distributed with Mac OS X) or Mozilla Firefox - to avoid download problems. What You Need to DownloadRequired filesTo install CIAO 3.4 you need the following packages - available from the platform-specific download pages, on the European Mirror Site, or on CD via the Helpdesk - for your machine:
The Installing CIAO 3.4 thread explains in detail how to install each of these software components. Optional filesThere are two optional packages - the source code and the OTS (Off The Shelf) collection of external programs/libraries used by CIAO - that can be installed. These are only needed if you wish to re-compile CIAO yourself. Users doing spectral analysis (e.g. line indentification) may also be interested in installing the Atomic Database (ATOMDB). The ATOMDB Download page has information on this package. |
