Don Cross	eec6e0b782	Removed obsolete Delta T code generator logic. ... We don't need to generate Delta T tables any more because none of the Astronomy Engine supported languages use it any more. Now they all use Espenak/Meeus polynomials instead.	2020-05-15 19:40:35 -04:00
Don Cross	f2ee3d38b8	Moved JPL Horizons file for DeltaT so it doesn't break unit tests. ... I downloaded the airless_Moon_dt.txt file from JPL Horizons so that I could reverse engineer their DeltaT function. But keeping it in the horizons directory caused unit test breakage. Moved to delta_t directory so dtplot can still use it to make graphs.	2020-05-15 14:16:11 -04:00
Don Cross	258b0572a0	Plot a graph of Delta T extrapolator versus generated function.	2020-05-15 13:05:00 -04:00
Don Cross	36643fc47a	Fixed #2 - use finer-grained delta-t values without discontinuities. ... Using historic, recent, and predicted values of TT-UT instead of UTC leap seconds. With linear interpolation, there are no longer discrete jumps in the calculated TT values. Hopefully, this will make event solvers (rise, set, etc) more well-behaved.	2019-04-14 16:42:50 -04:00
