I want to thank everybody who chimed in on this thread
about Leonard Gray's 100 problems, cocked hats, and
sight reduction methods. I have found it edifying.
I would be happy to compare my results to those
obtained by others.
I have a couple of questions:
+ Is there a copyright issue to posting the text of
one or several of these problems?
+ What about sight averaging? I have read recommendations
to plot the altitudes of three sights taken in rapid
succession and use an altitude/time average, or to find
a best-fit line of the proper slope. Here, folks seem
to prefer to plot the LOPs from all three sights. I suppose
this gives you some notion of the size of the error in the
individual sights. I find it difficult, when examining the
result, to decide where to mark an MPP, which is, I guess,
the point.
Leonard Gray does not give any notion of how close he feels
the student should come to his answer.
