Benefits of data challenges
Formulate observing strategy based on...
Ability to remove known instrumental effects
e.g., persistence, ghosts, jitterOnly useful until real data are released
Ability to recover input model parameterse.g., composition, thermal structureUseful throughout mission lifetimeInform TAC
Allocate observing time wiselyFacilitate pipeline algorithm developmentSlide9
