There are lengthy NavList threads about Doniol. So lengthy that I have decided to ask a question rather than search the archives. I had thought that there were three Doniol methods- sin as in Bowditch, the haversine-Doniol in thread titles and the Doniol-Rudzinski-Ix method. I have just conluded that the haversine-Doniol and the Doniol-Rudzinski-Ix methods are one and the same thing. Am I correct?
