I present an extension of the phase distance correlation periodogram to
two-dimensional astrometric data. I show that this technique is more suitable
than previously proposed approaches to detect eccentric Keplerian orbits, and
that it overcomes the inherent bias of the joint periodogram to circular
orbits. This new technique might prove to be essential in the context of future
astrometric space missions such as Theia.
