Download CHIANTI



The CHIANTI package is currently distributed in two ways: We recommend you to use CHIANTI within SolarSoft and to setup automatic upgrades. It is easy to follow the instructions to download and setup the package.


If you use CHIANTI as a stand-alone package


Both IDL and Python users should download the database files:

Please check the IDL and Python links below for what to do with the database file.

IDL users

Download the CHIANTI-IDL procedures below:

Once you download the database and IDL files, please follow the instructions for installation.

For more details on using the CHIANTI IDL routines, please consult the CHIANTI User Guide.

IDL users can download a set of population lookup tables that make some calculations much faster (see CHIANTI Technical Report No. 16).

Put them in a local directory and point to them with the environment variable $CHIANTI_LOOKUP.

Python users

ChiantiPy is distributed through GitHub (recommended). It is also available on the Python Package Index PyPI.

Please check the instructions on these pages to set up the database tar file.
