Fe XVII - VERSION 4.0

The CHIANTI database consists of 4 primary ASCII files for each ion in the database.

• fe_17.elvlc (energy levels)

  contains the energy levels in cm^(-1) It includes both experimental data and theoretical values of the levels energies.

  % Note: some energy levels from the NIST database, version 2.0, have been renumbered
          in order to match the identification given by Bhatia and Doschek
          and their theoretical energy levels. In particular, the following changes
          have been made:
                         NIST  -->  CHIANTI 
  			
  			12   -->     9
                          13   -->    12

• fe_17.wgfa (radiative data)

  contains wavelengths, gf and A values for each transition. Wavelengths are based on experimental level energies where available; wavelengths calculated from theoretical energies are less accurate and are given as negative values.

• fe_17.splups (electron collision data)

  contains the spline fits to the electron collision strengths scaled according to Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.
