The most up-to-date expected survey performances (previously called "experiment definitions"), and all the historical ones used for iterating, for both large-area survey and small-area survey, can be found at Survey Performance Expectations.
Expected Survey Performances (a result of instrument performance and observations) below are the converged result at each epoch (or will be once someone fills them in).
