Summary: 2D Fourier Projection and 2D Patterson Projection code and software?

[L. Cranswick]

Apologies for the delay on this - a belated summary on software
and code for 2D Fourier Projection and 2D Patterson Projection.

Jon Wright noted via E-mail that the CCSL (Cambridge Crystallography 
Subroutine Library) has this functionality via Fortran code.

"The Cambridge Crystallography Subroutine Library is a collection of 
many Fortran routines which will allow you to tailor your own application 
to do just about everything in crystallography."

>From Jon Wright:

>Lachlan,

>There is such a program for doing projections within CCSL (weren't you
>expecting me to say that?). Source is there, and I believe it can be built
>using g77 and pgplot (under windows too with the GrWin/Pgplot library).
>Snipped from the source is the following comment:
>
>C                           F O U R P L
>C
>C    GENERAL FOURIER PROGRAM, INCLUDING PLANE SECTIONS, PROJECTIONS, GENERAL
>C PLANE SECTIONS AND ERROR MAPS, WITH SAVING AND RESTORING FACILITIES TO/FROM
>C FILE, AND OUTPUT TO PRINTER AND/OR PLOTTER.
