Fe XXV d - VERSION 5.1

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

• fe_25d.elvlc (energy levels)

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

• fe_25d.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.

  %comment: theoretical energies have been used as experimental values for the dielectronic transitions
  %comment: V4.02 wavelengths have been replaced with Safronova's values to better match the 
            observations (E.Landi - Oct 2003).

• fe_25d.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.
