[sdpd] Re: Symmet - Chalk River Pole Figure Software for DOS
Preferred orientation information can also be very helpful for powder
indexing, by providing some degree of explicit supplementary information
about the zone-identifications of particular lines and groups of lines.
The old cylindrical Stubbins cameras used to be ideal for this, but
flat-plate photos can be useful too. The same may well apply, but of course
much faster, with modern area detectors (depending on their geometry).
