   %A values: Froese Fischer & Saha, 1985, Phys. Scripta 32, 181
   %comment: Theoretical energies were used by Froese Fischer & Saha to derive
   	 the transition probabilities, but as the theoretical energies
   	 tabulated in the above paper did not differ from the observed
   	 values by more than 0.5%, it was not deemed necessary to re-scale
   	 the A values to account for this.
   %comment: negative wavelengths have been computed using theoretical energy levels

  Collision strengths :

   %filename: ca_15.splups
   %oscillator strengths: are taken from "superstructure" using a 3
      configuration model of the ion, which was shown to closely match the
      'HF+2p4' oscillator strengths found in Aggarwal, 1983, J.Phys.B, 16, 2231
   %collision strengths transitions 6-46 : Bhatia, A.K., Doschek, G.A., 1993, ADNDT, 53, 195
   %effective collision strengths (transitions 1 - 15): Aggarwal, Berrington & Keenan, 1991, ApJS, 77, 441
   %comment: the authors regard their collisional model to be accurate to ~10%.
   %comment: effective collision strengths were given in the temperature range 5.0 < Log T < 7.0.

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

 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.
