pydown.py now searches description text for internal links
and expands them properly for Markdown file README.md.
For example: "#Body" ==> "[`Body`](#Body)".
Fixed a couple of incorrect "Astronomy_..." names in Python docs.
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.
Also had to adjust a couple of error thresholds.
Windows version of Python calculates slightly different
numbers than Linux version. Perhaps a difference in
runtime libraries?
The Microsoft C compiler/runtime for Windows is generating
slightly larger floating point discrepancies in the unit
tests. Adjusted the thresholds upward so all the tests pass
in Windows also.
Separate the calculation of refraction angle from the Horizon function.
Added missing documentation for the parameters of the Horizon function.
Added definition of class Spherical. Not yet used, but soon will be.
Instead of having the same calculations duplicated in both
nutation() and nutation_rot(), I reworked nutation() in terms of
nutation_rot(). Use nutation_rot() to calculate the rotation matrix,
then multiply that matrix by the input vector to produce the output vector.
The gcc-6 compiler in travis-ci has changed its behavior.
It is warning that 'fmid' local variable in Search() may
be used uninitialized. I believe it is safe but I'm adding
an initialization to fmid to make the warning go away.
This program demonstrates converting ecliptic coordinates
to horizontal coordinates at a given time for a given observer.
It searches for the two locations on the horizon where the
ecliptic plane intersects it.
I need a way to undo a refraction correction:
given a post-refraction altitude, find the unrefracted
altitude that leads to it. Starting to write the code.
Not finished yet.
These are the final 4 rotation functions to complete every
possible coordinate transform.
Finished unit tests of verifying that all triangular
cycles of transitive rotation are consistent.
