Yes, got it! Was just going to post that I had a look at the data.
The data looks great from my perspective.
For what it's worth, I have found that under good conditions (i.e. clear
conditions, not resting the sextant, no extremely low altitudes, no AH) my
measurements are typically within 0.7' most of the time (say 90% of the time) and
within 0.3' about a third of the time. This would be for individual
measurements.
If I sit in a lawn chair or support the sextant somehow, I seem to get a
little better result and tend to see results in the <3' most of the time. With
an AH I get some further improvements.
I realize this is far from a rigorous treatment of the data I have collected
but it seems at least in a qualitative sense to be similar to the experience
others have posted.
I have noticed that there can be some significant differences (0.3 at times)
depending on the source of the almanac data at times. I have a couple of
programs for my Palm T3, a PC program and of course the various on line sources.
To really analyze those errors that are <0.3' it's going to take a lot of
data!
