This is a fast rotation function which works in polar angles, written by W. Kabsch. These sections may be plotted as stereograms. The position of peaks is given for all symmetry related positions in both polar and Eulerian angles. However, the crystal symmetry is expressed less fully in polar angle space than in Eulerian angle space, so for cross-rotation functions the Eulerian program is normally more appropriate.
