Re: Moon total correction- round it up?

Um...where did you find a sextant that reads to a second, let alone a tenth of a second?

A second of arc is equal to 100 feet on the ground so a tenth of a second is only 10 feet!, celnav is not that accurate.

As to rounding, three seconds is 1/2 of a tenth of a minute, so 45 to 51 seconds rounds to 0.8 minutes and 51 through 57 rounds to 0.9 minutes.

Greg,

I was using the Moon correction data from Navsoft downloads. I have a copy the Moon ALt. Corr. tables from an old book but wasn't sure if they ever go out of date. Do they?

As to rounding off. If there's an Ho of 25d 37min 50.4sec should that be rounded off to 25d 37.9 ?

Thanks,

Sam L
