-====== Challenge 1 ====== 
  
-===== Equal mass cluster in isolation and in a tidal field ===== 
- 
-PI: Alice Zocchi\\ 
-Other participants: Mark Gieles, Vincent Henault-Brunet, Anna Lisa Varri, Antonio Sollima 
- 
-Questions to address: 
-  
-  - What is a suitable model to describe post-collapse clusters? We here consider 3 models: 
-        - Isotropic King (1966)  
-        - Anisotropic Michie King  
-        - $f_\nu$ [[http://adsabs.harvard.edu/abs/2003ApJ...584..729B|Bertin & Trenti (2003)]]; [[http://adsabs.harvard.edu/abs/2012A%26A...539A..65Z|Zocchi et al. (2012)]]  
-  - How much does tangential anisotropy/retrograde rotation due to the tides matter? 
- 
-The relevant snapshots from simulations of an isolated cluster and cluster within a tidal field are available in [[:tests:collision:mock_data|section A of the Mock data page]].
