• Preparatory Observations Program Status
• Radial velocity Strategy for follow-up
  observations
• Photometric Survey the BEST telescope
• Stellar radius estimation a critical problem

A lot of work has been done.. A lot has still to
be done
HARPS, CORALIE SOPHIE the guaranteed time will
not be sufficient Proposals to be submitted in
the open time
1 or 2 field(s) can be monitored per season
Expected accuracy 20???
COROT Asteroseismology results are urgently
required !!
3

• Complementary surveys
• Background contamination in the exofields
• Strategy for the follow-up observations should
  be set up during CW6

Jean Surdej will coordinate a XMM proposal mid
2004
Strongly dependent on the direction ?
anticenter 2 stars included in the PSF ? center
up to 15 stars included in the PSF, depending
the stellar density ..

Questions to the ExoSide

• Validate the fields list with priority levels
• Would you like to keep the possibility to
  re-observe the same field ?

Yes !!
Drift of the orbit or no drift?
Yes, after the nominal lifetime of the mission
