Made-to-Meaure Galaxia is an easy way for anyone to generate mock samples of stars from made-to-measure models of the Milky Way. The made-to-measure method adjusts an N-body model attempting to match it to a set of constraints. Usually this means adjusting an N-body model until it fits data in a maximum likelihood sense.
The modelling process is flexible and so can handle the non-axisymmetric bar and bulge, a region that is otherwise very difficult to model. All the models available here were fitted to Milky Way data from the central ~5kpc, with the result that they hopefully are good models of the inner Galaxy. Importantly the models are all dynamically self-consistent, meaning that the particles move in the gravitational potential that they themselves generate.
