Ananke: GAIA on FIRE
Plot type: Histogram bins the data by a single field and displays count of objects per bin. Heatmap bins the data by two fields and displays count as color. Conditional distribution bins the data by one field and displays the distribution of a second field within that bin as a boxplot (range and quartiles). Shows a scatterplot of a (random subset) of actual data points.
For log functionality, set the filter to enable only positive values.
For log functionality, set the filter to enable only positive values.
Count: Choose whether the object count per bin is shown in linear or log scale. Count is shown on the Y axis. Count is shown on the color (Z) axis.

About Catalog

Sanderson et al 2018.
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.
