A non-parametric higher-order Jeans analysis method, GravSphere, was recently used to constrain the density profiles of Local Group dwarf galaxies, classifying them into those that are more likely to have an inner dark matter cusp and those that are likely to have a core (Read et al.).

We parameterize the orbital history by the time since crossing within 2. 5 rvir of the cluster centre and use our catalog to estimate the probability density over a range of this parameter given a set of present-day projected (i. e. observable) phase space coordinates.
