All the data files provided consist of 6 columns: x,y,z,vx,vy,vz. Coordinates are given in kpc, and velocities in Km/s. text/html 2022-10-24T12:26:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://astrowiki.surrey.ac.uk/doku.php?id=tests:sphtri:results&rev=1666614419&do=diff Results Code Models run Results .tar.gz file (contains ASCII data) GravLite 1-8, 11-14 <https://github.com/PascalSteger/darcoda/tree/sphere/gravlite/output/spherical> MAMPOSSt 8 non-tangential (312 cases) <http://www.iap.fr/users/gam/GAIACHALLENGE/mamposst.tar.gz> (including ReadMe.txt) MAMPOSSt MAMPOSSt (Mamon, Biviano & Boué 2013) performs mass / orbit modeling by fitting the distribution of tracers in projected phase space (PPS: projected radius, line-of-sight velocity), assuming a … text/html 2022-10-24T12:26:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://astrowiki.surrey.ac.uk/doku.php?id=tests:sphtri:spherical&rev=1666614419&do=diff Spherical models Description of mocks These DFs are calculated for different potentials (`Cusp' or `Core'), different light profiles (`Plum' or 'Nonplum'; but note that even the `Plum' case is not quite Plummer as it has an inner slope with power-law index 0.1 instead of 0), and different velocity anisotropy profiles (`Iso', 'OM', `Tan' for isotropic, Osipkov-Merritt and constant tangential). text/html 2022-10-24T12:26:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://astrowiki.surrey.ac.uk/doku.php?id=tests:sphtri:tidal&rev=1666614419&do=diff Tidally stripped models 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.

It is valuable to know how a particular algorithm will perform when presented with observed data which do not satisfy the underlying symmetry assumptions of the algorithm. Full details of the mock data and how to use them are included in the data file tar bundle.
