The Chandra data-reduction package CIAO 2.0 can be obtained below. Since some of the files are quite large, I've placed them on the IfA web site to save time. I have also included the patch files to take them to CIAO 2.0.1 (released 12/08/00) - this upgrade is only urgent if you use the tgextract tool, but it's small so you may as well! Whilst the Linux version will probably run on any recent Linux distribution, it has mainly been tested on Rad Hat 6.x and Slackware 7.x.

Please see the CIAO README file for installation instructions. With this version of CIAO, the calibration data has been moved into a separate package - the CALDB - which you will also need to install if you intend to do anything but the most basic of tasks. Currently, the only local package is the main part of the CALDB installation. The rest can be obtained either using the links to the left or from the CALDB download page. If you do get any of these files, let me know so I can put them on the web site. Please read the CALDB README file carefully, as not all files are currently up to date.

CIAO 2.0.1 (patch, 12/08/00)
Install this after you have CIAO 2.0.

CIAO 2.0 (12/04/00)
You need the Aux file and the binary distribution.

CALDB (12/04/00)
  • README
  • Main Release (45 Mb, REQUIRED)
  • ACIS PSF (174 Mb, NOT A LOCAL LINK!)
  • HRC PSF (186 Mb, NOT A LOCAL LINK!)
  • FEFs (needed to make RMFs)

    • See README for FEF information. A new version of the FEF library is coming soon which greatly reduces the number of files you need. Here is a local copy of the (old) -120 degree C version - it's only 11 Mb.

ACIS Background Files (11/27/00)
Maxim Markevitch's background dataset + tools to use them (Solaris only, but source code is included) are available here (95Mb compressed). See this page for more information (including if there has been an update); you can also access the background datasets individually here, which will save you some space.
