9df1a7a128 Added documentation for JavaScript function Constellation. 2020-05-04 13:37:11 -04:00
Don Cross
4d81c4324f Shrank minified JS code to 76338 bytes. 
Represent DeltaT table entries as lists rather than objects.
This makes them more compact in the minified code.

e7e9d1bb78 Shrank minified JavaScript to 76978 bytes. 
Represent constellation name/symbol pairs as lists rather than objects.
This makes the representation more compact.

762bf08f66 Shrank minified JS code more: from 80904 to 77329 bytes. 
Store each constellation border as a list rather than an object.
This makes the encoding more compact.

9a6005bf24 Shrank minified JavaScript from 86423 bytes to 80904 bytes. 
Changed the units of the angles stored in the constellation
borders data so that the numbers can be represented more compactly.
This requires converting the numbers back at runtime, but this is
well worth the smaller size.

e80b5a45d0 Updated npm package version to 1.0.5: supports EMB, SSB. 
Astronomy Engine now supports calculating heliocentric
Solar System Barycenter (SSB) and
Earth/Moon Barycenter (EMB).

f754a6de82 Fixed #58 - Solar System Barycenter, Earth/Moon Barycenter. 
Can now calculate the heliocentric Solar System Barycenter (SSB)
and Earth/Moon Barycenter (EMB).

Changes made in C, C#, JavaScript and Python:
Added new body codes SSB, EMB.
Added support for calculating both in HelioVector functions.
Verified that all calculations match NOVAS.
Verified that all calculations match each other across languages.

60db741717 Ported planetary apsis search functions to JavaScript. 2020-01-07 14:09:45 -05:00
Don Cross
02dc4e95a4 Pluto apsis predictions are now within 0.0810 degrees of orbit period. 
Increased from 7 Chebyshev sections to 8.
This also decreases max arcmin error from 0.336084 to 0.120252.

f67ddf1c8d Planet apsis: all planets but Pluto now have prediction error below 0.1 degrees. 
Adjust VSOP models for planets to bring their prediction errors beneath
0.1 degrees of a total orbit.
ctest no longer runs tests when no command line arguments are given.
That was annoying because I kept running it by accident.

819e59745d Decreased Neptune apsis prediction errors from 49.25 days to 15.45 days. 
Include an extra 4 terms in the radial component of the VSOP
model for Neptune. The code automatically picks the 4 terms
that maximize the time derivative's highest possible contribution.

7040ff8684 Cleaned up documented return types for Python functions. 
Never use pound-signs inside documentation for Python return types.
Automatically create internal link just like for function parameter types.
Added special case logic in pydown.py for "Time or `None`".
Fixed minor documentation mistakes in JS version.

f2478fa29d Improved performance in C and JS code by getting rid of ter2cel() function. 
I already did this in the Python code to significantly reduce the number
of calls to e_tilt(). Did the same thing here: call sidereal_time() once,
then use the value 3 times.

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.
