===== Full N-body models (with local cuts) =====

These are full collisionless N-body simulations. The first two were published and analysed in [[http://adsabs.harvard.edu/abs/2011MNRAS.416.2318G]] and [[http://adsabs.harvard.edu/abs/2012MNRAS.425.1445G]]. The latter two include a perturbing satellite at low and high inclination. 

There are four simulations:

Each simulation includes: 

  * densityfalloff_dm/stars :: ASCII file data for the dark matter/star density fall-off at different radii and angle for small volumes around the disc. 
  * surfacedensity_bar/dm :: As above for the surface density for the baryons and dark matter.
  * velocity dispersion :: As above for the stellar velocity dispersion in the z-direction (perpendicular to the disc).
  * wedges :: Raw unbinned ASCII data for different wedges cut around the disc as in [[http://adsabs.harvard.edu/abs/2011MNRAS.416.2318G]].
  * *.txt.gz :: Raw ASCII data for the entire centred and aligned simulations (excluding the accreted satellite stars and dark matter). **Warning**: These files are large (>2 GB). 
  * *.tip :: Tipsy format binary file containing **all** simulation data. **Warning** :: these files have not been centred or aligned. Tools for reading, centring and aligning these data can be found in the PyNbody suite [[https://github.com/pynbody/pynbody|here]].
