As the Antarctic Winter nears its end, I managed to obtain the apparent sun altitudes, as found [below, see PS]. The apparent position corresponds to the observed altitude.
All times UT
Height of eye 0
IC 0
Normal refraction.
Wanted, latitude and longitude
The sun transits my meridian during the data set.
The data is NOT randomized. The apparent altitudes represent true and actual USNO data, rounded to the nearest 0.1' for the precise time listed.
Just as in Frank's data set, the declination of the sun is changing. It's up to you to determine that value.
Since NavList insists that anything else is cheating, I do believe you have all the data you need.
Mr. Reed's criteria: "one can expect a latitude accurate to a mile or so, and a longitude accurate to +/- three to seven miles"
Good luck!

PS: Note from FER: there was a problem with Brad's original data which was in a pdf attachment, so I have placed his data directly in the message, as above.
