ok the paper explains how to use boh vector mode and rotation mode.  the 
wikipedia page is, as usual, a lot easier to understand than the academic 
paper from which huge amounts of information are missing in order to keep 
it short and acceptable for publication in space-limited journals *sigh* :)
