In Sects. 4.3 and 4.4, uncertainties were not properly taken into account in the computation of the scaling relation between mode widths (Sect. 4.3) and effective temperature for main-sequence stars (MS), and of the scaling relation between mode amplitude and effective temperature, again for main-sequence stars (other scaling relations are correct). The correct results are

ΓTeffswith{s0.3±0.9forRG(unchanged)s16±2forMS(corrected)\begin{equation*} \Gamma \propto T_{\rm eff}^s \quad \mbox{with} \quad\left\{ \begin{array}{lll} s \approx -0.3 \pm 0.9\; &\text{for RG } & ({\rm unchanged}) \\ s \approx 16 \pm 2 \; &\text{for MS } & ({\rm corrected}) \end{array} \right. \end{equation*}and: AmaxI(LM)swith{\begin{eqnarray*} A_{\rm max}^{\rm I} \propto \left(\frac{L}{M}\right)^s \; \mbox{with} \; \left\{ \begin{array}{lll} s = 0.92 \pm 0.14 \, &\text{for RG } & ({\rm unchanged}) \\ s = 0.42 \pm 0.14 \, &\text{for MS } & ({\rm corrected}). \end{array} \right. \end{eqnarray*}The corrected values are only slightly changed and well inside former uncertainties. Moreover, the corrected uncertainties are smaller than the former ones. Figure 7 is also slightly changed (see Fig. 1). The conclusions remain unchanged with these more precise results.

Measured mode linewidths versus Teff for the red giants (Teff < 5000 K) and for the main-sequence stars (Teff > 5000 K). The dot-dash line indicates the fit to the red-giant width and the triple-dot-dash line the fit to main-sequence stars.

Acknowledgments

This wrong computation was pointed out by T. Appourchaux who performed a thorough check of the former published results.
