Dear Colleague,

We would like to announce the release of version 6.0 of the CHIANTI database for astrophysical spectroscopy. With Version 6, CHIANTI includes ionization and recombination coefficients for the calculation of ion fractions, as well as software to read and handle them. CHIANTI 6.0 also improves the calculation of He-like line intensities. The data for the Be-like and F-like sequences, including the key ions
Fe XVIII and Fe XX, have been updated. Data for many other ions havebeen updated and new ions have been added to the database. Ion fraction datasets from recent calculations are also included.

If you use CHIANTI through SolarSoft, the update will occur automatically within a day or two, if you have the SolarSoft mirror set up.

If you use CHIANTI through the stand-alone tar file, we recommend that you download and install the new tar file in your CHIANTI directories. The new tar file can be found at our web sites:
