...UT is studied and adjusted using ancient astronomical observations and following Morrison and Stephenson (2004) for the interval 9999 BC700 BC, the difference TT−UT (which, for our purposes we can assume as TDB−UT) follows a parabolic relationship such that for BC10000 = 1/1/- 9999 = JD−1931076.0…...
