-===A. [[:​tests:​collision:​method_comp|Method comparison]] (now Challenge #4):=== +
-Jeans modelling vs. Distribution-function based models for fitting mock data of GCs. +
-We will start with $N$-body snapshots of the M4 models by Heggie (2014): http://​datashare.is.ed.ac.uk/​handle/​10283/​618+
  
-===B. Understanding Gaia errors:=== 
-What will Gaia actually give us (for GCs, open clusters, runaway stars, hypervelocity stars)? What can we do with TGAS? 
  
 +Throughout the Gaia Challenge I-III workshops, we have tackled four specific challenges:
  
-===CPotential escapers:=== +**1Single mass clustersthe interplay of anisotropy and tides (Zocchi et al. in prep)**
-aquantify biases from ignoring them+
  
-b) towards self-consistent mixture ​models ​with potential escapers+**2. Clusters with a mass spectrum: testing the validity of multi-mass models ​(Peuten et al. in prep)**
  
 +**3. Observational biases (Sollima et al. 2015)**
  
-===DRotation:=== +**4Method comparisonJeans modelling vs Distribution-function based models**
-include prescription for rotation in multi-mass DF models.+
  
 +Many of the challenges make use of LIMEPY ([[http://​arxiv.org/​abs/​1508.02120|Gieles & Zocchi 2015]]) developed in the context of the Gaia Challenge.
