Downloading CIAO 4.13 and CALDB 4.9.6

Please be aware of the following issues before installing CIAO 4.13 (see the watchout page for more information):

• Classic CIAO 4.13 only supports Python 3.7

• macOS users must install recent versions of XQuartz and XCode.

• CIAO 4.13 does not support 32-bit Linux, CentOS6, or macOS Sierra (10.12) and earlier.

• Fontconfig error: Cannot load default config file can be ignored as long as the test reports PASS.

• There is a known bug in the check_ciao_version script in the 4.13.0 contrib release.

Verify conda version. Users should be using conda version 4.7.6 or newer.

$ conda --version
conda 4.8.3

If conda is not installed,

$ conda --version
conda: Command not found.

users can install miniconda from the Anaconda website.

Install CIAO into a new conda environment.

$ conda create -n ciao-4.13 \
  -c https://cxc.cfa.harvard.edu/conda/ciao \
  ciao sherpa ds9 ciao-contrib caldb_main marx

Users may also wish to includes packages such as jupyter, astropy, and scipy into their new CIAO conda environment.

Activate the CIAO environment

tcsh% conda activate ciao-4.13
  or
bash$ source activate ciao-4.13

By default, the terminal prompt will change to show the currently active conda environment. Users can also run the ciaover command to verify that they are setup correctly.

(ciao-4.13)$ ciaover -v
