Dear authors,

Thank you for your revised submission. The four reviewers had positive impressions of the first version of your manuscript, and I agreed; after reading your response to reviewers and revised manuscript I feel that you have addressed their comments adequately. I am therefore pleased to accept your manuscript for publication in AMT. This is an important topic and I feel you have made a good contribution towards understanding colocation uncertainties here.

I note one of the comments and responses was to the effect of figure/font size, and that you had increased the font size/line thickness and would consult with me concerning figure size. Final figure size will be controlled by the Production Office (and you can discuss with them during the typesetting process) but I imagine that the initial proofs would have the figures at the same size as the source files. Checking through the figures, the font sizes are still somewhat small and may be hard to read if figures are reproduced at this size in the final version. My suggestion is therefore that, when submitting final files for production, you upload new figures with an increased font size by another several points. This may save time and effort later in the typesetting and layout process (as if figures are re-sized later, typesetters may have to lay out pages differently). For this reason I have suggested publication subject to technical corrections. Please let me know if you have any question.

Best wishes,

Andrew
