Nature of problem:
Orientation of a 4-circle diffractometer with a single crystal sample, fixed detector and standard Eulerian arcs.
Using identifiable Laue reflections that pass close to the counter (but not necessarily into its centre), the orientation equations are solved directly or by least-squares fitting (as appropriate).
There is no restriction on the symmetry of the sample. The maximum number of allowed data points is controlled by a PARAMETER statement and set at 20 in the distributed version.
Less than 1 second.
