1Ephemeris Longitude is the terrestrial dynamical longitude assuming a uniformly rotating Earth. 2True Longitude is calculated by correcting the Ephemeris Longitude for the non-uniform rotation of Earth. (T.L. = E.L. + 1.002738*deltaT/240, where deltaT(in seconds) = TDT - UT) Note: Longitude is measured positive to the East. Since deltaT is not known in advance, the value used in the predictions is an extrapolation based on pre-2002 measurements. Nevertheless, the actual value is expected to fall within +-0.5 seconds of the estimated deltaT used here.
