| + | ====== Priority order of runs ====== | ||
| + | |||
| + | We realise that the above mocks about to a very large number of tests which for some methods may be prohibitive. For this reason, if you can only run some of the tests the priority order is as follows: | ||
| + | |||
| + | * Spherical isotropic models viewed along z with velocity errors and 10,000 stars. | ||
| + | * Spherical radially anisotropic models viewed along z with velocity errors and 10,000 stars. | ||
| + | * Spherical tangentially anisotropic models viewed along z with velocity errors and 10,000 stars. | ||
| + | * The above with lower sampling (1000 stars; 100 stars). You may prefer to do the sampling tests just for one system in which case start with the isotropic models, as above. | ||
| + | * Split component models (if your method is capable of this; again with velocity error). | ||
| + | * Triaxial models with velocity error and 10,000 star sampling. Try projections along X (long axis); and the intermediate axis I. | ||
| + | * Tidally stripped models with velocity error and 10,000 star sampling. | ||
| + | |||
| + | In all cases **projections should be along the z-axis**. | ||
