CHIANTI consists of a critically evaluated set of up-to-date atomic data, together with user-friendly programs written in Interactive Data Language (IDL) and Python to calculate the spectra from astrophysical plasmas. The CHIANTI package is freely available. If you use the package, we only ask you to appropriately acknowledge CHIANTI .
- The Chianti wine-producing area of Tuscany, Italy -	Version 11.0.2 of the CHIANTI IDL routines released, August 2025 This minor update to the CHIANTI IDL routines fixes a bug when computing spectra from the advanced models for isothermal plasmas. The advanced model software has also been updated to allow atmospheric parameters to be input through a structure (see CHIANTI Technical Report No. 33). Solarsoft users should update their distribution, otherwise the CHIANTI IDL routines can be downloaded from our download page.
We are grateful to individual scientists and funding agencies for their support.
