Both referees write that the paper is much improved and recommend publication after minor revisions. Please consider their recommended revisions and provide a revised version of the paper and a response making it clear which revisions you have made and which you have not made (with brief reasons) for the latter. I then expect to be able to accept the paper without further consultation with the referees.

Both referees recommend that your paper is now accepted subject to minor/technical corrections. (Each referee has given a short list of recommended corrections.) Please can you provide a further revised version of the paper, with brief responses to the referees making it clear which changes you have made and which you have not. I expect then to accept the paper for publication without further consultation with the referees.

I am pleased to accept this version of your paper for publication in ACP.
