2D Visualizations

These images show ROCKSTAR halos as white dashed circles and the FoF halos as colored tiny dots. You can see how the FoF halos have tend to have non-spherical arbitrary shapes. The ROCKSTAR objects, on the other hand, tend to define boundaries around rounder objects. With time, the sizes and shapes of the ROCKSTAR objects are a lot more stable than the FoF ones which exhibit more variability, e.g. the addition of the tail to the Pokemon in Snapshot 99.
