8a34da0540 Made C GeoPos consistent with JS GeoPos. 
The algorithm for light travel correction was not consistent
between JS and C. Now the output is consistent between the two.
Still interesting that the angular error decreased when I incorrectly
backdated the Earth's position as well as the other body's.

b78a6ffa4c Found one discrepancy: was not using the same latitude in both tests. 2019-05-18 23:02:56 -04:00

f0f7db74dd Added ad-hoc tests to find discrepancy between JS and C code. 
The JS and C SkyPos functions are calculating slightly
different values. It looks like the C code is actually
a little more accurate. I want to understand why.

82ba5efecc Made time values match between c_check and js_check. 
This is one step closer to adding a check for identical
output between the JS and C calculation checks.
I still see discrepancies that need to be resolved,
but the time values are all now identical.

e450e702d0 Made changes to JS and C unit tests so that "check" files are diffable. 
Now temp/js_check.txt and temp/c_check.txt are in the exact same format.
This reveals interesting discrepancies between the two calculations
that need to be resolved. There should be very tiny differences, if any,
between the respective outputs of the C and JavaScript tests.
In fact, that should be another part of the unit test.

bf2eeed105 Implemented C version of Horizon function. Fixed bug in C GeoPos. 
The C version of GeoPos was returning an ante-dated time value,
not the time the caller asked about. In other words, it was
returning the time when the observed body emitted the light
the observer sees, not the time the observation was made on the
Earth, like it was supposed to. Fortunately, my unit test caught that.
