What are you talking about? The speed of light does *not* depend on the
inertial observer. Its the same for all inertial observers (in flat
spacetime)

...it would be impossible for me to
model these light curves, which are real and taken by thousands of amateur
astronomers.

Then define your quantities. All I see are diagarms with no labels on the
axes to tell what quantities are being plotted.
