◆ RotationElements::PlanetCorrections

struct RotationElements::PlanetCorrections

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)

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

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

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

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