Abstract:

This QuickBASIC program plots stereographic projections, CBED and
HOLZ line simulations, and performs axis/angle pair calculations.  
Output is to the screen or a Hewlett Packard HP 7470A Plotter.  Stereographic 
projections are drawn to scale for subsequent manipulations with a standard 
18cm. Wulff net and can be plotted for cubic, hexagonal, tetragonal and 
monoclinic crystal systems in any orientation.  Plotted poles can be 
restricted to those allowed by structure factor considerations (for certain 
structures) or restricted to those in certain Laue zones.  The program 
leads the user through menus to determine the structure and orientation  
for the projection, which is then plotted accordingly.  Version 4.00 is 
significantly enhanced compared to earlier versions.
