Then I'm not sure that I understand what exactly the problem is.  Can 
you state it in terms of what you start with and what you expect to get?

The only clue I see is "Now I want to rotate these to a well defined 
status, so that I can can compare them."  Which is where I understood 
you to want to compare them.

You might check at http://www.catb.org/esr/faqs/smart-questions.html
