Data release v- ____-__-__.
The ananke framework, which generates realistic synthetic stellar surveys from cosmological baryonic simulations, was used to create a set of synthetic phase-space surveys designed to resemble Data Release 2 of the Gaia astrometric survey from different solar viewpoints in the Latte suite of FIRE-2 simulations of Milky Way-mass galaxies. The synthetic surveys are described in detail in Sanderson et al 2018. The full dataset is available here.
