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…

After discussion with Magali: low density in the south, i.e. go rather north…

ConclusionsConclusions
E. Michel COROT field evaluation mai 04, IASE. Michel COROT field evaluation mai 04, IAS
Using Corotsky + complementary informations on secondary candidates,+ exo-field criteria
For each field: 6-8 “specific” objects, among which ~3-6 observable together to be completed to 10, for ~ half of it with:
mV<8 informations avaliables8<mV<9.5 information not yet available
can the present list can satisfy scientific expectations? Yes
We can propose more precise fields: Yes, SOON, for some of themProposal for summer 04 based on available infos (seismo+exo)
eventually what should/could be added, how and when…: Stromgren photometry for complementary stars with mV-> 9.5 available mid 2005,To confirm the choice
