Method Detail

calcCoord

public static void calcCoord(double jd,
                             Body body,
                             double precision,
                             boolean velocities)
                      throws AstroException

Calculation of Moon coordinates.

Parameters:

jd - julian date ; time scale : dynamical time TDB.

body - a Body whose index is at SolarSystemConstants.MOON.

velocities - Flag indicating if velocities must be also calculated.

Throws:

ComputationException - if a computation was asked for an instant not handled by ELP82.

AstroException - if the data for the computations are not loaded.

getPrecision

public static double getPrecision(int bodyIndex,
                                  double jd)

Returns the precision of the calculation for a given julian day and a given body.

Parameters:

bodyIndex - Integer specifying for which Body the precision is asked ; use

jd - The julian day for which the precision is asked. SolarSystemConstants.

setDataPath

public static void setDataPath(java.lang.String dataPath)

Sets the path to data used by ELP82 to perform the computations.
