Referee #2: The authors have replied to all my concerns. However there are a few minor changes that should be addressed before publication. After the authors make these little changes, the article is ready to be published.

1) P8 L20-21. Crooked sentence.

2) P9 L25-27; P11-14-15, and p11 L33-34 and P12 L1. If the histogram approximates a normal distribution, why the data fail the test for normality? I think authors should decide whether they believe or not their data follow a normal distribution or not, indicate the p-value of the Shapiro-Wilks test and act in consequence. If the data do not follow a normal distribution, the mean $\pm~1~\sigma$ may not be the best index of central values and spread of the data.

3) Although the article improves with the addition of confidence intervals, authors must use them to decide the number of significative digits they show. For instance, Fig 14, c), slope is 0.94 (0.94, 0.94). Clearly, authors can (and should) provide more digits to this value. This is just an example, but this approach should be used in the whole article. Deciding an arbitrary number of 2 decimal digits is not a good approach.
