The derivation of the damping rate in the long wavelength limit by Yu et al. (2017) is incorrect. This was already noted independently by Sadeghi and Karami (2019) and by Roberts (2019, priv. comm.). What follows is the correct derivation. The sign of P0 (A.7) in Appendix A was incorrect. Equation (41) should read

and for Eq. (43)

where we have only retained the first term (see Eq. (C.1) below). Equations (44) and (45) should then read

These expressions for γ0 are the same as those obtained by Roberts (2019) by using a different approach.

Equations (C.1), (C.3), and (C.4) in Appendix C should read

and

Damping rate |γ0|/ω versus kzR for slow sausage surface mode (ss) where l/R = 0.1. The other parameters are the same as in the previous figures. For the linear cusp velocity, we compared the analytical formula, Eq. (35), with the simplified formula in the long wavelength limit, Eq. (45).

It should be noted that the values of the quantity |γ 0|/ω in Fig. 5 are small as can be understood from the equation for |γ 0|/ω for the values of k z R ≤ 0.4 used in Fig. 5.

We note also that eight in the second paragraph after Eq. (10) and 8 in the caption of Fig. 1 should read four.

Acknowledgments

We are grateful to B. Roberts for pointing out the error in our manuscript. Equations (41), (43)–(45), (A.7), (C.1), (C.3), and (C.4) were wrong in our paper.
