AAAUUUGGGHH! I seem to be flooding the list with my mistakes. I found
an error in my altitude calculation that changes the results a bit
(although it still appears that this is the mystery star). The
following table should replace the previous one:
clr'd d true d
GMT PI 6 Orion
5.094 59.768 59.605
5.323 59.829 59.705
5.493 59.902 59.795
5.589 59.911 59.831
5.643 59.995 59.865
5.694 60.010 59.888
7.267 60.622 60.625
7.362 60.698 60.680
7.419 60.679 60.698
7.490 60.687 60.732
7.525 60.716 60.757
7.571 60.718 60.770
Here the error in the first series is about 4' and the error in the
second series is about 1.4'. Sorry to all for my lack of diligence.
