However, the latter concept, minimum symmetry, requires that two topics be reviewed, Miller indices and **stereographic** projections. Fundamentals (Assumed Background) Miller Indices Directions and planes are reported as integers enclosed in brackets (sometimes the brackets are omitted by convention).

•The **stereographic** projection contains orientation information about all poles that intersect the northern hemisphere of the sphere. •Poles such as (01-1) and (00-1), which intersect the southern hemisphere of the sphere, are not included in the [001] **stereographic** projection.

Polar **Stereographic** projection and ArcView Spatial data on this CD-ROM are in Polar **Stereographic** projection. This projection was chosen for the following reasons: 1.

A **stereographic** projection has two important properties which make it particularlv suitable for crystallographic and universal stage work. First, the projections of both great and small circles are circular arcs and not ellipses.

THE UNIVERSAL POLAR **STEREOGRAPHIC** (UPS) SYSTEM UPS coordinates are based on a family of two Polar **Stereographic** map projections, one for each pole.
