Science Verification¶

Science Verification provides an end-to-end test of all the systems needed to actually conduct the survey, both on the mountain and elsewhere. Successfully passing the formal acceptance requirements is a necessary condition for DES to begin (along with corresponding acceptance tests of DES DM and the Community Pipeline).
