Notes.Since the sausage mode introduces longitudinal structuring we show values for rays 1 (node) and 2 (anti-node) for geometrical quantities. The amplitude denotes the maximum variation in time with respect to the value at t = 0 of the quantity considering all parameters. The unit corresponds to percentage except for the Doppler velocity where it denotes the maximum value, and the χ² parameter, where it denotes the variation in orders of magnitude. A range in the values of the quantity corresponds to variations between the models. The values in the other columns denote the factor by which the variation in the quantity is modified when varying the specific parameter of the column. The direction of the parameter variation is indicated in the column head. Up and down arrows (or both) denote, respectively, an increase or a decrease (or both if non-monotonic) by the specified factor as the parameter is varied. An asterisk indicates that the variation in time of the quantity is negligible for the initial value of the parameter. Values in parenthesis correspond to some relevant values for the base model − 193. The last column corresponds to the possible observed period in the specific observed quantity, with P the period of the sausage mode.
