Dear Fred, I just posted my second series of Lunars made 2 hours ago. (Taking into account all advises I got on the first series) > Even with that bad point in there your mean is -0.2' > from the truth > with a standard deviation of 0.7', > and a standard error of the mean of > 0.3'. Usable. But do you agree that that bad observation HAD to be rejected? It was evident to me immediately when I read my sextant. My reason and all what I know about statistics imply this. I suppose the reason of that blunder was incorrect time recording. My (easily solvable) problem is that I have no watch that I can read in the darkness and without eyeglasses. So I am just thinking of buying a good large diameter split-second-hand stop watch, as in Bruce Bauer, page 141. (I see some of these in my favorite Ukrainian web store:-) In the observations I reported I used the "Old Flegmatic British Merchant Mate" method as described in Bruce Bauer, same page:-) > It looks like you made the right choice > getting that snowy sextant rather than a Husun. I also like it. Still have to try really large distances. (It allows to 140 degrees!) I am afraid I will need another place than my balcony for this:-) Alex.
