NavList:

It dawned on me that what I thought was the problem you were pointing out was not it at all (although I will still change the words).  To use this to check the use of the azimuth graph I need to show angle in quadrant (in this example, 60.5º), not azimuth angle as I have shown, since the graph only goes to 90º.  I just don't know what to call it, as what I was taught was that azimuth angle Z could be up to 180º.  Unfortunately, the example in the article of using hav-Doniol to calculate azimuth (the one on the "index card", that should not have been included in the article) shows a Z greater than 90º, which could    I guess I still have to call it Z and say something in the "Help".

Look for Beta3 soon.   (This is why it is still a beta .)
