Figure 15 in Ito et al. (2019) did not include two panels, Figs. 15d and 15e, that were mentioned in the text and caption, and labels indicating points A, B, and C in Fig. 15c were not properly placed. The corrected figure is presented here. The errors do not affect the results and discussion. We regret that these mistakes occurred during the preparation of the final typescript and were overlooked through proofreading. The authors apologize for any inconvenience.
