  PROGRAM AUTHORS - A. D. Murray and A. N. Fitch.


  TO RUN PKFIT :

    Simply type "pkfit" from the directory containing your
  diffraction data file, and you will be prompted by the program
  for all the information it needs, i.e.;

    * name of data file,

    * data file type,

    * approx peak position,

    * peak shape position ( Gaussian, Lorentzian, pseudo-Voight, etc. ),

    * choice of background function,

    * option of using asymmetry parameter.


    Wherever a choice from several options is required, a single
  "RETURN" generates a list of the possible options.

    Details of the quality of fit follow the execution of the program.
