0.21+: Axes of planets and moons require terms depending on T=(jde-J2000)/36525, described in Explanatory Supplement 2013, Tables 10.1 and 10.10-14, updated in WGCCRE reports 2009 and 2015.

Others require frequent updates, depending on jde-J2000. (Moon etc.) These should be updated as frequently as needed, optimally with the planet. Light time correction should be applied when needed. best place to call update is the SolarSystem::computePlanets()

Member Typedef Documentation

◆ axisRotFuncType

typedef double(* RotationElements::axisRotFuncType) (const double, const double)

Finetuning correction functions.

These functions are attached to the planets in Planet::setRotationElements() and called at the right places. This avoids ugly sequences of name query ifelses. arguments are d=JDE-J2000, T=d/36525, J2000NPoleRA, J2000NPoleDE

Member Function Documentation

◆ corrWJupiter()

static double RotationElements::corrWJupiter	(	const double	d,
		const double	T
	)

static

The default W delivers SystemII longitude.

We have to shift by GRS position and texture position. The final value will no longer be W but the rotation value required to show the GRS.

◆ getMarsMagLs()

static double RotationElements::getMarsMagLs	(	const double	Ls,
		const bool	albedo
	)

static

Retrieve magnitude variation depending on angle Ls [radians].

Source: A. Mallama: The magnitude and albedo of Mars. Icarus 192(2007) 404-416.

albedo true to return longitudinal albedo correction, Ls=the average of sub-earth and sub-solar planetographic longitudes false for the Orbital Longitude correction. Ls here is the apparent solar longitude along Mars' "ecliptic". (0=Martian Vernal Equinox)

◆ updatePlanetCorrections()

static void RotationElements::updatePlanetCorrections	(	const double	JDE,
		const PlanetCorrection	planet
	)

static

Update the planet corrections.

planet=3(Moon), 4 (Mars), 5(Jupiter), 6(Saturn), 7(Uranus), 8(Neptune). The values are immediately converted to radians.
