c611b50d3f Significant performance boost to Python code: eliminate _ter2cel(). 
There were 3 calls to _ter2cel(), each of which redundantly
called _sidereal_time, which results in 3 calculations of _e_tilt().
Reworked so there is only one call to _e_tilt().

Minor changes to support using cProfile, which is how I found this.

f85025da31 Implemented astro_check in Python. Exercises major parts of the code. 
There is still a slight discrepancy in calculations of altitude,azimuth
that is larger than between JS and C.

07ba91ed65 Use same code generator for JavaScript and Python: Chebyshev Pluto model. 2019-06-26 05:25:09 -04:00
Don Cross
027a6af007 Adapted JS vsop code generator to work with Python code too. 
Now the Python code and the JavaScript code for VSOP models
are generated by codegen.c using the same $ASTRO_LIST_VSOP macro.
Python functions for calculating from VSOP are not yet implemented.

44b9d26d1d Python: CalcMoon work in progress. First pass is finished. Not yet tested. 2019-06-24 14:48:08 -04:00
Don Cross
79df146194 More Python CalcMoon work in progress. 
Also made minor optimizations to spin() function in both JS and C.
Fixed a mistake in JS and C that does not appear to have any
algorithmic consequences, but it was definitely confusing once I saw it.

Don Cross
18251d16a4 Added another C example program: positions.c. 
This example demonstrates how to calculate equatorial coordinates
and horizontal coordinates of solar system bodies.

Added explanatory comments to moonphase.c.

Added #defines for MIN_YEAR, MAX_YEAR in astronomy.h.

Removed unnecessary code from positions.html; no longer need
to calculate geocentric vector before calculating equatorial coordinates.

e0a119426a Correct for aberration when calculating angles seen from Earth. 
Resolved FIXFIXFIX comments regarding whether or not to
correct for aberration. In all cases, the observations are
made from the Earth, in which case it makes the most sense
to correct for aberration.

3f60d2fac1 Added documentation for Astronomy_LongitudeFromSun and Astronomy_MoonPhase. 2019-06-05 19:23:25 -04:00

5a1cb85318 Fixed #44 - Renamed relative_longitude to ecliptic_separation. 
I was using "relative longitude" to mean two different things.
Resolved the ambiguity by using relative longitude only for
differences in eclitpic longitude as seen from the Sun.

Use "ecliptic separation" for differences in ecliptic longitude
as measured from the Earth.

Fixed completely wrong documentation in the JavaScript code;
it had the meanings backwards inside the ElongationEvent class.
