Dear Dr. Philipp Joppe,

I have received the review report from one referee (Referee # 3) for the revised version of your manuscript. This referee thinks that some issues he raised in the first round of review are not well addressed. The major concern of the referee seems to be on Fig. 5 and associated data treatment, and he pointed out that the data from different instruments were inconsistent. Please read the referee’s comments and questions carefully and give your responses. Please try to address all the issues the referee raised and make necessary revisions of your manuscript.

Sincerely,
Jianzhong Ma
