Gentlemen,
I just tried to use Sight reduction Astron spreadsheet / manual option and can't locate Altitude correction for Sextant sight. Also, Index error shows only minus option. But if it is (-) should I add it instead of subtracting it from Hs? . When I entered the Height of eyes in meters the spreadsheet calc simply subtracted this number from Hs, not the data I saw in Nautical Almanac ( hard copy). Anyway, I got a little bit different results for azimuth and intercept.
My question is: should I blindly trust the spreadsheet or paper/pencil approach? Yes it is much faster.
Again, difference about +/- 1.5 deg. in azimuth and tolerable in the intercept results. Thank you.
