I am hardly learned enough to speak to terrestrial refraction anomalies.
Read through the Frank's beach shots from Indiana thread.

Alex replied:

I did. I found no talk on anomalous refraction,
and Frank was apparently satisfied with his observation
(based on the difference of height of two Chicago buildings).
I found the beginning of this trend on October 10.
Am I missing something?

Bill

Yes, and possibly. Yes, the thread began on Oct 6th.  Possibly, there was a
time when the list crashed, and Frank and I carried on intercourse off list
until it was once again functional. I do not recall if this was the subject.

Alex responding to George:

But I suppose that the physical conditions you are
talking about were not present in Kielerforde on that day.
The water was very cool (and always is) here.
I mean most people do not dare to swim in Kiel till the beginning of
August:-)
But the air was hot, at least that was what I felt:-)

Alex, large snip:

The observations I posted included BOTH upper and lower limb.
There was no difference: the error was -3.5 in the everage,
independent of the limb.

Bill

Sorry, I missed the fine print on upper- and lower-limb observation, as
well as exactly what standard you were using to determine a negative result.
(I still don't have an answer.)

Then heck Alex, you are screwed!  None of the possible explanations pass
your tests no matter how you sign your results. Your multiple glowing posts
of your reductions (unless you are having a problem in sub 0.3' accuracy)
and my observations of your abilities would indicate you cannot be at fault,
waves cannot be at fault, dip cannot be at fault, refraction anomalies
cannot be at fault, and on-and-on ad infinitum.  Your mathematically acumen
is certainly not the problem. It must be hard to be perfect in a flawed
universe. 

That leaves us with only two possibilities:

1.  By some twist of fate, the planet earth (and possibly the universe) is
conspiring against you and repeatedly sending you seriously flawed sextants.

2.  It may be past time to deep six your "superior" and beloved Casio.

I suspect your choice of professions was, all said and done, extremely wise.
