fe_17.wgfa (radiative data)

contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

fe_17.splups (electron collision data)

contains the spline fits to the electron collision strengths scaled according the rules formulated by 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.

%oscillator strengths: Landi & Gu, 2005, ApJ, in press
%Collision strengths (all levels): Landi & Gu, 2005, ApJ, in press
%Effective collision strengths (n=3 levels): Gu, M.F., 2003, ApJ, 582, 1241
%Comment: effective collision strengths from Gu (2003) have been summed to the distorted-wave
   collision strengths from Landi \& Gu (2005).
%Comment: effective collision strengths are given in the temperature range 1.16e6 < T < 5.8e7
