   %upsilons (ground configuration, levels 1 to 5): Lennon, D.J., Burke, V.M., 1994, A&AS, 103, 273

   %collision strengths (all other transitions): Bhatia, A.K., Doschek, G.A., 1995, ADNDT, 60, 145
   %comment: The Lennon & Burke upsilons are tabulated between logT=3.0-5.0, and the
        T_max of Mg VII is 5.7. The Aggarwal data go up to logT=7.7. I've thus
        used all of the Lennon & Burke data and appended the Aggarwal data for
        temperatures logT=5.2-7.6. It was necessary to scale the Aggarwal by
        the ratio of the Lennon & Burke data to the Aggarwal data at logT=5.0
        to ensure a smooth join between the two data-sets. The scale factor
        varied from 0.82 (4-5) to 1.19 (1-5).
        The fits to the ground configuration upsilons are accurate to 1.2% over
        the temperature range logT=3.8-6.2.

 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.
