Hello, I am using Starry Night Pro for archeoastronomy. Can you tell me the actual calculation used for the (very ancient) Earth pole location (circa 12,000 BC)? Comparing Starry Night to my own calculation, using a longterm earth pole motion model from the astrophysical literature, I get about 0.3 degrees difference, over that timeframe (14,000 years). Thank you.
How does STARRY NIGHT PRO calculate the ancient pole of Earth?
