Moon Orientations Incorrect(?)

[stratochief66]

Due to built in KSP issues all planets (other than Earth) will not appear to have the correct inclinations.

However, the orbit of the moons should still line up with the plane of the ecliptic (I believe)

Currently, Mars, Jupiter, and Saturn appear to use different conventions, I am unsure which one is accurate.

The moons of Mars are not in plane with Mars' equator or the ecliptic.

The moons of Saturn are in plane with the equator (and rings), therefore not in plane with the ecliptic

The moons of Jupiter are in plane with the ecliptic, therefore not in plane with Jupiter's equator (I believe this to be correct as it is most similar to Earth's moon. but I could certainly be wrong)

I am not good enough at planetary orbital mechanics to correct this, but hopefully pointing this out in detail will be useful.

When I wrote the new moon's orbital parameters, they were done relative to the planet, not to the Sun or ecliptic (the figures come from HORIZONS with the planet as the reference frame), so I'd expect that's why Saturn's are correct to the planet (it certainly would look odd if the moons weren't near the same plane as the rings). Same for Neptune and Pluto.

Jupiter and its moons however, was written by ThomasKerman I believe, so @NathanKell should probably comment which convention should be done here.

Can a change be applied to the planets alone to correct their axial tilt to the correct KSP settings (i.e. compensating for the approx 23.4 degree offset due to KSP's locking of Kerbin/Earth? If so, if the moons are specified correctly (i.e. relative to the planet using HORIZONS), they should follow?

@NathanKell bump :)

Phobos should not be in line with the ecliptic but roughly with Mars's equator.
Wikipedia (aka The Truth) says:
Inclination 1.093° (to Mars's equator)
0.046° (to local Laplace plane)
26.04° (to the ecliptic)
