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 avaliables  8<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 them  Proposal 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
