Tools developed by helioseismologists and by classical-pulsator astronomers have been used in the hare-and-hound exercises for having a several different ways of deriving the oscillation mode parameters such as frequency or amplitude. These tools are used for deriving what we call recipes that will allow us to obtain the mode parameters from light curves either for solar-like stars or for classical pulsators. The recipes are used for tagging the mode parameters as being those of COROT. They will be used as reference or yardstick for other fitting strategies. We will also address the issue of mode detection. Additional tools such as time-frequency analysis will be presented.
