    Not so mammoth a task. The new version was printed from a pdf file. A difference between the current edition and those issued previously by the government is that the pages of the main table are generated images rather than vector files. The full file from which the printed volume was generated is many gigabytes in size. There is also a version of the pdf with much reduced resolution in the page images. It's fine for screen use and much more "portable" in size, but its pages would look "ratty" when printed (so if you want a nice non-electronic version, you should just buy one of the printed copies direct from Celestaire). Last I heard, Ken Gebhart was still deciding how and when to release the lower resolution pdf file.

    As for that "nice fellow" working on the pdf file, thank you! That would be me. All of the altitude and azimuth data for the selected stars were sourced directly from US Naval Observatory software. It would have been easy for me to calculate these directly (and I did that for every single case to double-check the numbers), but the key is that the volume requires a "legitimate provenance" so that they would not become "some guy's" version of publication 249.
