At the present stage of the COROT preparation programme, this activity is also intended to bring indications and criteria to optimize the field selection. The procedure and some results were reported during the COROT-SWG-Milestone2000 meeting and are available in the proceedings (see the reports of Appourchaux Th. et al., Berthomieu G,. Provost J.). They showed that interesting things could be learned from such exercises but it appeared that this was a first very simplified step and that it was worth performing a more realistic exercise which would involve the two groups. This imply more relevant oscillation spectra for synthetic light curves to be analysed and more relevant precision on seismic parameters used for seismic interpretation.
Thus the responsibles of the two groups tried to work out a second hare-and-hound exercise which consists in constructing simulated time series which represent as well as possible the observation of a puslsating star by COROT. These time series are then used to extract the frequencies and interpret them in terms of internal structure and rotation of the star.
