NavList:

I have read the various threads on this subject.  Things became clear when I read that Classic-Ageton is the sin formula worked by a modified Ageton table and that Ageton-Bayless is the same method as Ageton but with compacted tables. I also noted reference to hav-Doniol which I will follow up.

I have also solved another problem that has bugged me for many years. I have been Windows free (Linux) for ten or fifteen years but have never been able to run Windows programs under Wine. I was keen to run CelestialTools and so decided to give Wine another go. Initially I did not have any success until I realised from an error message that CelestialTools is written in Visual Basic. I downloaded the dll listed in the error message and the program is now running.

There is still thick cloud outside so I will probably work some Classic-Ageton sights after lunch.
