Detailed Description

Contains the functions that set up the planetary system configuration.

In addition, the last two functions allow to track the first planet (number 0) of the planetary system, in order to perform a calculation in the frame corotating either with this planet or with its guiding-center.

real GetPsysInfo	(	PlanetarySystem *	sys,
		boolean	action
	)

The original function was modified to handle 3D inclined orbits.

It is similar to the one used in fargo3D but employs tools from the REBOUND package.

real GetPsysInfoFromRsim	(	struct reb_simulation *	rsim,

An analogue of the GetPsysInfo() function; here a rebound simulation structure is used as a call argument.

void RotatePsys	(	struct reb_simulation *	rsim,

	)

Synchronises the planetary system with the frame.

Affects the rebound simulation structure only, 'sys' and 'rsim' are synchronised later on.
