+The macro below lets you insert freely-refined peaks at values determined by h,k,l of a specified unit cell.  It's only written for orthorhombic, tetragonal or cubic systems, but you could modify the dsp equation for other systems.  It uses a single overall lorentzian mixing.  You can optionally restrain the intensity to known values.  Enter 0 and penweight 0 if you don't want to do this.
