  A Values
  Nussbaumer and Storey (Ast and Ast 96, 91, 1981) did Superstructure and
  close coupling calculations. For allowed transitions there is close
  agreement between the results and reasonable/understandable differences
  with earlier results. Their results used for 1-3, 1-4, 1-5, 1-6, 1-9, 2-8,
  2-10, 3-7, 4-7, 5-7, 6-7 and 7-9.
  For the intercombination result they took care and results are available
  in the length formulation from Superstructure. More recently Lennon et al
  (Astrophysical J 294, 200, 1985) recalculated 1-2 and 1-3 results. For the
  allowed transition the agreement with the result of Nussbaumer and Storey
  is good (at worst a difference of 8 parts in 470). The intercombination
  results are different (74 cf 55.3 s-1 or 12.4 cf 5.24 at worst). Preferred
  the data of Lennon et al for 1-2 transition. Use of their results gives
  better agreement with solar results.
  For 10-11, 10-12 and 10-12 use the results from Weise, Smith and Glennon
  (NSDRDS NBS4 1966).

   11-14 to 16, 12-16, 13-15 and 13-16 and 2-15 and 2-16 are from HPS

  Collision  Rates
  Lafyatis and Kohl (Phys Rev 36, 59, 1987) measured the 1-3 cross section.
  Their measurements from 1 to 2 times threshold energy agree with the
  results of Robb (Magee et al, LA 6691 MS 1977) within the experimental
  uncertainty. Also agrees with Hayes and Nussbaumer (Ast and Ast 134, 193,
  1984) whose calculation was as Hayes (as given in O IV write up). Data are
  available for 1-2, 1-3, 1-4, 1-5, 2-3, 2-4 and 2-5 transitions. The results
  of Robb (op cit) were used for 3-4, 3-5 and 4-5. This was a five state
  close coupling calculation using single configuration wavefunctions and
  Clementi orbitals.
  Lennon et al (Mon Not Roy Ast Soc 220, 571, 1986) have done a recalculation
  of the earlier Lennon et al work allowing for a change of the energy
  position of a resonance. They say there is in general quite good agreement
  with the the results of Hayes and Nussbaumer with a few exceptions,
  especially 2P1/2 - 2P3/2, but this does not affect the populations.
  For 1-6, 1-7 and 1-9 use the results of Mann (Magee et al, op cit) who did
  a unitarised Coulomb-born calculation with exchange, with and without CI.
  For 2-8, 3-7, 4-7, 5-7, 6-7 and 7-9 used impact parameter.
  For 2-10 to 16, 10-11, 10-12, 10-13, 11-14, 11-15, 11-16, 12-16, 13-15
  and 13-16 used HPS Born results.

     Dielectronic data is post-processed from Badnell files as follows:

          /JETSHP.BADNELL.BELIKE(C2LS22)
          /JETSHP.BADNELL.BELIKE(C2LS23)

     The cross-referencing file is as follows:
