Downloading CIAO 4.2
The ciao-install script is designed to simplify and automate the installation and upgrade of the CIAO and the Chandra Calibration DataBase (CALDB).
ciao-install FTPs the selected files to your computer, verifies them via md5sum, and unpacks them. The script configures CIAO, sets up the command-line ahelp system, and (optionally) runs the CIAO smoke tests.
The ciao-install.README file had detailed information on the script. For a summary of options, run the script with the "--help" option.
This method allows ciao-install to determine what platform you are using, then downloads and installs the standard CIAO installation: CIAO tools, ChIPS, Sherpa, the main CALDB tarfile, and the contributed science scripts.
For existing CIAO installations, this method may also be used to download and install software patches and contributed science script updates.
This option will not choose one of the beta 64-bit builds even if you are on a 64-bit system. To install 64-bit CIAO, use the Custom Installation option.
Run the script:
unix% bash /<path>/ciao-install
For detailed instructions, refer to the ciao-install thread page.
If you are having problems using the ciao-install script, refer to the Manually Installing CIAO 4.2 thread. It explains how to retrieve the files with wget and then install CIAO step-by-step.
