I don't know who generates these files... but I would not be surprised if that was built by someone who needed at that time and never needed it again... And no one else has had the courage to run the code to build the new values.  The CHIANTI in ssw ([at least in HESPERIA](http://hesperia.gsfc.nasa.gov/ssw/packages/chianti/HISTORY)) is v7.0.  That kind of confirms my theory :-/
