Dear Colleague,

We would like to announce the release of version 7.0 of the CHIANTI database for astrophysical spectroscopy. With Version 7.0, CHIANTI now includes data for several new ions as well as significant updates to many ions, including several key Fe species routinely observed by Hinode/EIS and SDO. Also, a completely new implementation of the CHIANTI software in the Python programming language has been developed and is freely available on the web (ChiantiPy). IDL software updates have been performed to ensure compatibility with IDL 8.

If you use CHIANTI through SolarSoft that is automatically mirrored, the update will occur automatically within the next few days. Otherwise, you will need to manually update your the SolarSoft directories.

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 new web site location:

http://www.chiantidatabase.org/ - note the new url!

The ChiantiPy software suite can be found at

http://sourceforge.net/projects/chiantipy/

If you have any questions, problems, suggestions regarding CHIANTI, we are always glad to hear from you by sending email to

chianti_help@halcyon.nrl.navy.mil

Best regards,

The CHIANTI Team
