I just want to clarify my previous message. In the Nautical Almanac there is a TAble of Altitude correction. Based on Apparent altitude you get correction for Sun sight, Stars, and Planets.. It is written over there Apparent Altitude=Sextant altitude corrected for index error and dip. Now, using the spreadsheet, I got corrections for dip. Also I have index correction. But in the case of the Sun I also need to have Apparent altitufde correction for low /upper limb. And that's what I can't locate in the spreadsheet. Am I missing it?
