  Transition probabilities from the critical data compilation
  'Atomic Transition Probabilities of Carbon, Nitrogen, and Oxygen'
   by W.L. Wiese, J.R. Fuhr and T.M. Deters,
   J. of Phys. and Chem. Ref. Data, Monograph 7, 1996.
   Note the accuracy of the data is discussed and presented.

  Effective collision strengths from Aggarwal and Keenan, Ap J SS
  123,311-349,1999 Data scanned in and expanded as recommended by the
  authors.  R Matrix calculation up to 13 Ryd. All partial waves L=< 40
  included. Note that comparisons wih earlier work show the collision
  strengths to be the same but there are some differences in the effective
  collision strengths. The ealrier efective rates have been shown  to be
  in error.  They say their work is 'fairly accurate' (**??**) for
  transitions involving the lowest 40 levles. For transitions invovlving
  the higher levels the accuracy 'is less' (**?**). They also point out
  improvements could be made by improving the wavefunctions by adding more
  configurations (1s2 2s2 2p2 1D and 1D levels should then be in better
  agreement with experiment).  This affects resonance positions and hence
  results at  lower temperatures.  Inclusion of relativstic effects will
  also help, especially for  fine-structure collisions between levles of a

  4-6 and 5-14 tramsitions had no colision data. Since A values were available,
  they were entered and the collision values set to 1.00-30. The paper says
  collison strengths for all transitions were available, but it turns out that
  not all effective collision strengths were published.  Apart fromthe 2 already
  mentioned 5-6,6-13,15,19,23,27,28,32,33,36,44,45,46 and 14-27,33,46 are
  missing.  Level 6 is quintet andtransitions involving this to singlets are
  omitted as well a from the quintet to a 3S1 level. The missing transitions
  involving level 14 are all S to S.
