There are some typos in the text that discusses the vertical spectrum trends given in Figs. 5 and 6. The vertical spectra shown in these figures are computed for median + sigma. To this end, the wording “median” in the last paragraph of page 530 and first paragraph of page 531 should be replaced with “median + sigma.”

There is also another mistake in Fig. 8 and the corrected version is given in Fig. 1. This mistake does not affect our results or conclusions in the paper.
