An array to receive the cartesian position (x,y,z) and the derivatives.
This array must be large enough to store the results.
- PVAJ[1:3] contain the position (x,y,z) and is always valid.
- PVAJ[4:6] contain the velocity (dx/dt,dy/dt,dz/dt) and is only valid if order is greater or equal to 1.
- PVAJ[7:9] contain the acceleration (d^2x/dt^2,d^2y/dt^2,d^2z/dt^2) and is only valid if order is greater or equal to 2.
- PVAJ[10:12] contain the jerk (d^3x/dt^3,d^3y/dt^3,d^3z/dt^3) and is only valid if order is equal to 3.
The position, velocity, acceleration and jerk are expressed in Astronomical Unit (au) if unit contains
UNIT_AU
.The position, velocity, acceleration and jerk are expressed in kilometers if unit contains
UNIT_KM
.The velocity, acceleration, jerk, TT-TDB, TCG-TCB or the derivatives of the angles of the librations of the Moon are expressed in days if unit contains
UNIT_DAY
.The velocity, acceleration, jerk, TT-TDB, TCG-TCB or the derivatives of the angles of the librations of the Moon are expressed in seconds if unit contains
UNIT_SEC
.The angles of the librations of the Moon are expressed in radians if unit contains
