auto shamphys::get_binary_pair ( double  m1, double  m2, double  a, double  e, double  nu, double  G  )

inline

Convert a binary system from Keplerian to Cartesian coordinates.

This function calculates the positions and velocities of two objects in a binary system using their masses, semi-major axis, eccentricity, and true anomaly.

Parameters

m1	Mass of the first object.
m2	Mass of the second object.
a	Semi-major axis of the system.
e	Eccentricity of the system.
nu	True anomaly of the system (in radians).
G	Gravitational constant.

Returns

A tuple containing four elements: the positions of the two objects and the velocities of the two objects.

		double	G,
		double	roll,
		double	pitch,
		double	yaw
	)

Rotate a binary orbit by Euler angles and return the positions and velocities of the two objects.

Parameters

m1	Mass of the first object.
m2	Mass of the second object.
a	Semi-major axis of the system.
e	Eccentricity of the system.
nu	True anomaly of the system (in radians).
G	Gravitational constant.
roll	Rotation about the X-axis (in radians).
pitch	Rotation about the Y-axis (in radians).
yaw	Rotation about the Z-axis (in radians).

Returns

A tuple containing four elements: the rotated positions of the two objects and the rotated velocities of the two objects.
