* Yet another test/exploratory class.HEADmasterDavid A. Madore2012-04-191-0/+36
|
* Re-add (rewritten) functions to compute Smart97 functions.David A. Madore2012-04-192-0/+28475
| | | | (This is intended as a test, not to be actually used.)
* Add a computation of zonal tide effects on UT1 (from IERS conventions).David A. Madore2012-04-183-0/+276
| | | | Plus a Test2 class which tests this on the TAI-UTC difference.
* Handle UTC between 1961 and 1972 ("rubber seconds").David A. Madore2012-04-181-5/+45
|
* Slight improvement to test proram.David A. Madore2012-04-171-1/+9
|
* Test: Compute final solar coordinates.David A. Madore2012-04-171-0/+7
|
* Various small fixes + add a simple test (computing solar coordinates).David A. Madore2012-04-175-3/+109
|
* Use J2000 ecliptic (rather than equatorial) coordinates as starting point ↵David A. Madore2012-04-172-2/+5
| | | | | | for precession. We will assume that these are the coordinates returned by VSOP87.
* Use quaternions instead of 3*3 matrices to represent rotations.David A. Madore2012-04-033-54/+46
|
* Equation of the origins/equinoxes.David A. Madore2012-03-273-1/+45
|
* Nutation.David A. Madore2012-03-274-3/+2493
|
* Use generalized Poisson series for VSOP87.David A. Madore2012-03-272-2506/+2524
|
* Implement more general Poisson series.David A. Madore2012-03-271-14/+77
|
* Simple matrix library + formula for precession.David A. Madore2012-03-275-439/+111

* Initial commit. This version doesn't do much but evaluate VSOP87/Smart97 ↵David A. Madore2012-03-276-0/+3196
