  This is a composite data set for high temperature use formed from

        Kingston et al. (1989)    HLIKE.DATA(AEK89H)
        Callaway et al. (1987)    HLIKE.DATA(CALL87H)

  using a three parameter fit with the first two Bethe coefficients
  fixed -  obtained from

        Golden, Sampson & Goett   S#HDATA.TEXT      (nb *2)

  Preferred data is taken from large scale comparative figures for the
  transitions from the 1s state.  The decisions on the preferred data
  is rather arbitrary, but makes use of the 1/n**3 scaling rule in
  circumstances where the original data is dubious.
  The compilation prepared by

        Giovanardi et al. (1987)

  is also shown in these diagrams but does not appear to be of much

  For transitions from n = 2 - 3, the extrapolated fits to Callaway are

  For transitions from n = 3,4 - 4,5 the extrapolated fits to Kingston
  are used.

  Data for the degenerate transitions due to electrons are taken from
  Kingston et al. extrapolated as ln(Te)
