-For these models, we set up a spherical two component (stars/dark matter) "dwarf-like" galaxy that we then throw on at a host Milky Way-like galaxy on a range of orbits. The initial conditions and modelling follows similarly to [[http://adsabs.harvard.edu/abs/2006MNRAS.367..387R|Read et al. 2006]]. The initial dwarf **before infall** has a Dehnen profile for both the stars and the dark matter: +For these models, we set up a spherical two component (stars/dark matter) "dwarf-like" galaxy that we throw at a host Milky Way-like galaxy on a range of orbits.

 +  * Files are numbered by the sampling e.g. _10000 is 10,000 stars and by the random draw from the full distribution e.g. _10000_0. **As with the spherical mocks, you should model by default including the 2km/s errors and using the _0 then _1, _2, _3 files in order**. (i.e. if you can only afford to run a single tidal mock for each orbit, then you should run the _10000_0_err file projected along the z-axis.)
