One does not need to know all these variations, and even less f-ratios:-)
Just look at your error column with your naked eye.
In lunar-1 your error varies from -0'2 to +1.8 and it is at least 1'
in almost half of all observations.
In lunar-2 the error is always between -0'3 and +0'3. And it is between
-0'1 and +0'1 in more than half of the shots.

Without any knowledge of statistics you can tell that lunar-2 is excellent,
and lunar-1 is "so-so":-)
Usually a lot of practice is required to achieve such progress.

Is Cape St Diego the most Eastern end of Tierra del Fuego?
Google maps does not react on "Cape St Diego".
If my understanding of what is Cape St Diego is correct than the author
of the footnote has the latitude wrong:-)

Which raises a general question:

Do there exist any GOOD geographical maps on the Internet?
I mean the maps which have
islands and straits and capes names in the uninhabited areas like Canadian
Arctic, for example. I recently read a book on Polar exploration, the book
did not have
good maps and I started looking on Internet. Google gives contour maps
of those areas without any labels of islands, straits, capes and other
geographical features. And to my surprise I was unable to locate any
reasonable maps.

 Alex.
