Dear folks,

Here is the next version of our IJoC paper, together with the Supporting 
Online Material and the detailed response to the comments of Reviewers 1 
and 2.

There is one small issue I'd like to discuss. As I mentioned in a 
previous email, I have now applied the "new" d1* test suggested by 
Francis [see equation (12) in the revised manuscript] to synthetic data. 
Results are shown in Figure 5B. I've also applied the "new" d1* test to 
observed and simulated T2 and T2LT data (see Table 3 in revised 
manuscript). I have not yet applied the new d1* to the modelled and 
observed surface-minus-T2LT difference series. The d1* results in Table 
6 are the OLD d1* results - not the new d1* results.

In practice, because the first term under the square root sign in 
equation (12) is small relative to the second term, the new d1* results 
are very similar to the old d1* results (which only involved the 
standard error of the observed trend in the denominator). So the "old" 
d1* results currently shown in Table 6 will probably not change by much 
when I complete the "new" d1* tests with the modelled and observed 
surface-minus-T2LT difference series. I should have those calculations 
completed on Monday morning, and will revise Table 6 then.

I'd very much like to resubmit our manuscript on Tuesday of next week, 
so that I can enjoy my birthday untroubled by thoughts of sigma{SE}, 
further sensitivity tests, etc. Please let me know if you think Tuesday 
is an unrealistic target for resubmission.

We owe Francis a big debt of gratitude. I think that his review comments 
(and his help over the past few days) have led to substantial 
improvements in our paper.

With best regards,

Ben
