These files created using AtomDB database v3.0.4. 
They represent the ionization and recombination rates from AtomDB
3.0.4.

Note that to make a full spectrum you need to update both the
eigenvector files (this tarball, to get the correct ionization
balance) and the emissivity files (from the AtomDB website, to get the
line emissivities and wavelengths) to create a full spectrum.

Ionization and recombination rates have not changed from 3.0.4 to
3.0.5 and 3.0.6 (i.e. the numbers are the same, so we have not
recreated the files).

To use the data in XSPEC, you must:

(1) Extract all these files to the folder:
$HEADAS/../spectral/modelData/

(2) Make sure you are using XSPEC 12.9.0t or later. If you need to
patch XSPEC, see the XSPEC issues page at
http://heasarc.gsfc.nasa.gov/docs/xanadu/xspec/issues/issues.html

(3) set the NEIVERS to 3.0.4 within XSPEC:
 xset NEIVERS 3.0.4
