GaussianRVInitializer

class ssapy.rvsampler.GaussianRVInitializer(rMean, vMean, rSigma=np.float64(4216417.236450565), vSigma=np.float64(307.46599995993046))[source][source]

Bases: object

Generate position and velocity samples as an isotropic Gaussian distribution around an asserted position and velocity.

Parameters:

rMean (array_like (3,)) – Mean of sample positions in meters.
vMean (array_like (3,)) – Mean of sample velocities in meters per second.
rSigma (float, optional) – Standard deviation of sample positions dispersion in meters.
vSigma (float, optional) – Standard deviation of sample velocity dispersion in meters per second.
