  Searches for un-modelled burst gravitational wave signals return potential
candidates for short duration signals. As there is no clear model for the
source in these searches, one needs to understand and reconstruct the system
that produced the gravitational waves. Here we aim to reconstruct the source
motion and masses of a system based only on its gravitational wave strain. We
train a normalising flow on two models including circular orbits and random
unphysical motion of two point masses. These models are used as a toy problem
to illustrate the technique. We then reconstruct a distribution of possible
motions of masses that can produce the given gravitational wave signal. We
demonstrate the ability to reconstruct the full distribution of possible mass
motions from strain data across multiple gravitational wave detectors. This
distribution encompasses the degenerate motions that are expected to produce
identical gravitational wave strains.
