Andrés:
You don't have to thank me for making the paper available. I believe you can thank the hosts of the conference for that and also the AAS (American Astronautical Society). :) By the way, in addition to the formal papers, the discussions of the papers and the roundtable discussions are ALSO very interesting, maybe more so. All of the preprints and the discussions are available here:

You wrote:
"I think you mean the difference is parallax correction for altitude"

If I understand you correctly, then yes. I haven're re-read my paper in three months, but I recall one other technical error. That is, I recall noticing it, but I don't remember what it was! :) In any case, I don't think it was anything that interfered with the main point, or any of the minor points. Thinking about this in the weeks before the conference, I could have stood up before the assembled astronomers and said, "Hey it's no problem for celestial navigation. It's just a time offset. Publish it annually in the Nautical Almanacs. Thank you for having me." But that would have been a little obnoxious so I used my time to tell a story: my spin on the interaction between different kinds of timekeeping and celestial navigation through the past couple of hundred years.

There's a group photo from the conference here:

For those of you who haven't met me, I am second from the right, wearing blue jeans. And yes, my eyes are closed (ha!). Two other names that I know some NavList members recognize: George Kaplan is on the far left wearing glasses and a brown coat and Ken Seidelmann is in a dark coat and blue tie three over from me (next to the Hubble guy in the stylin' hat). I got five of these guys to shoot lunars the previous evening at the hotel, and George Kaplan, who wasn't staying in town, also shot some from his porch at home with his Davis plastic sextant. You can probably find "astronomy rock star" Neil deGrasse Tyson in the photo on your own.
