  1. Evaluation of the Corot candidate fieldsincluding secondary candidates for long runs • Objectives: • Using Corotsky + complementary information on secondary candidates, • Go through the list of candidate fields (ref document january/04) in order to estimate to which extent: • information on Corot fields is sufficient to evaluate their scientific interest • the present list can satisfy scientific expectations • We can propose more precise fields • eventually what should/could be added, how and when… E.
