INPUT FOR PROGRAM HKSCAT

   Purpose:  Prepare reflection data files for use in other programs.

   CARD* 1	FORMAT ( 6 F8.2 )

		A, B, C, ALPHA, BETA, GAMMA in Angstroms and degrees.

   CARDS* 2-7   FORMAT ( 4X, I4, 9 F8.5 )

		J, ( A(J,K), B(J,K), K = 1, 4 ), C( J )

                Where J = integer atom type code.  The remaining 9 values 
                are coefficients for an analytical approximation to the
		scattering factors, taken from Int. Tables,Vol. 4,Page 99

                Coefficients for 8 atom types must be supplied.

   FILES

     UNIT    DESCRIPTION

      11     Formatted file with records containing h, k, l, FOBS, 
	     sigma of F.  In FORMAT ( 5X, 3 I4, F10.2, F6.2 )
	     This file must be supplied.

      20     Binary output file with records containing h, k, l, FOBS,
             sigma of F, sin (theta/lamda), ( FI( I ), I = 1, 8 ),
             AFIX, BFIX

             NOTE:  h, k, and l are packed in one word.

             Where the FI array contains scattering factors for 8 atom 
             types.  AFIX and BFIX are "fixed atom" contributions to the
             structure factor.  (May be used for hydrogen atoms, anomolous,
             etc.)
