Thank-you for your revised manuscript. Now I am asking for technical corrections, mainly to clarify the meaning but in one case (end of section 3) to include your response about “how long” in the paper.

Please note that your text will be copy-edited and I expect there will be changes to the English. Therefore you should look carefully after copy-editing to see that the text still says what you want.
