   %comment: Theoretical wavelengths for levels 1-54 are obtained from the SUPERSTRUCTURE calculation

   %A values (levels 55-172): A SSTRUCT run performed by P.R.Young.
   %comment: the A values for transitions between levels 55-172 have been calculated using a
       configuration model of Fe X in SSTRUCT. The configurations included were:

       3s2 3p5,  3s 3p6,  3s2 3p4 3d,  3s 3p5 3d,  3p6 3d
       3s2 3p3 3d2,  3s 3p4 3d2
       3s2 3p4 4s,  3s2 3p4 4p,  3s2 3p4 4d
       3s2 3p4 4f,  3s2 3p4 5s,  3s2 3p4 5p
       3s 3p5 4s,   3s 3p5 4p,   3s 3p5 5s

   %Collision data for transitions to levels up to 54: Del Zanna,  Berrington, Mason, 2004, A&A, 422, 731
   %collision strengths for transitions to levels 55-172: Malinovsky et al., ApJ 235, 665, 1980
   %comment: Maxwellian-averaged collision strengths have been calculated in the temperature range 2.5 10^5 - 10^7 K
   %comment:      Although for many of the transitions involving levels >62 there
        were gf values available, they have been fitted as Type 2
        transitions. This is because, as Type 1 transitions they were often
        difficult to fit (the 1-89 transition is a typical example).

        Some of the 4s transitions (levels 55-62) showed unusual shapes
        in the omega structure (e.g., 2-56, 1-58). I'm not sure how
        trustworthy this data is.

 Filtered adf04 file to 
  - sort energy levels 
  - remove non physical A values from
    energy level reversals
  - remove energies above ionisation potential
  - remove duplicate transitions

 Producer : Martin O'Mullane

 Regenerated to use the standard ADAS temperature set.

 Add the transitions in the CHIANTI source which have a transition
 probability but no accompanying effective collision strength and
 set these upsilons to zero.
