  This file tabulates the collision strengths on a fairly standard
  grid, however care should be taken when using this ADF04 type 1
  file, and any other type 1 file, because the tabulation may not
  be fine enough to form a well defined convolution with the
  distribution function being used.  More information on this can be
  obtained from the compiler of this data set.

  This data incorporates the neutral helium R-matrix calculation of
  Ballance (2003).  This calculation included detailed representation
  of the resonance region.  Interval averaging techniques were used
  to convert the OMEGA file produced by the R-matrix calculation to
  a manageable size (Paton, 2003).

  The main differences between this data and previous ADAS preferred
  data lies at low energy.

  This data comprises components from the following workbooks
         (1) he0_excitation_1s(1S)-nl().xls
         (2) he0_excitation_2s(3S)-nl().xls
         (3) he0_excitation_2s(1S)-nl().xls

  The workbooks contain historic comparative assessments of helium
  data and ADAS preferred data sets.  The workbooks are available
  to identified data assessors for further study.
