Sep 21, 2009 Dear Peter, As promised earlier to-day, I could take the time to closely verify and check the data in NavList 9823. They seem to be all correctly typed. I also re-ran both examples directly from the data published in NavList 9823. Both results fully agree with my earlier and former results. Here are the results I get : DENEB Transit Time, i.e. DENEB exactly North of moving Vessel occurs at 16h32m31.3s Position at 16:30.0 UT is N4208.5E006533 and it was (by chance) 0.7 NM away from our TRANSIT FIX at 16:30 UT. Our confidence on this astronomical fix was a Latitude error of 0.3' and Longitude error of 1.96'. (3 SIGMA values) RIGIL KENT Transit time at 09h17m52.3s (R KENT exactly south of moving vessel) Position at 09:30.0 UT is S4815.7W01709.4 while we had an other independent FIX off 1.4 NM from Astronomical FIX. Our confidence for this Astronomical Fix was a Latitude error of 0.3' and a Longitude error of 3.8' (3 SIGMA values). Well, I will admit that this one is kind of unique in many respects. But it did work out quite well. This concludes my current recent series of contributions to NavList. I will probably not be able to catch up with any replies for the upcoming week.
