  values (see ).
  Dahl2000 notes "The physical constants used in version 6.0 and 7.0
  are from the 74th edition of the CRC Handbook of Chemistry and
  Physics [12] Values of these physical constants (e.g. c, electron
  mass, and elementary charge) are defined to 8 or 9 significant place
  accuracy".  The 74th edition (1993-1994) uses CODATA1986, which were
  the latest CODATA values at that time.  SIMION 8.0 also uses these
