[Frost] [EXTERNAL] Re: Brief history of the FROST pi0 E-observable

[Stuart Fegan]

Hi Mike,

Thanks for taking the time and trouble to remind us all of the timeline 
of the pi0 E analysis.  As you probably found in your digital 
archaeology project, very little write-up exists of the old GW analyses 
beyond Hideko's thesis, and even less in the way of code.  Chan's had to 
start over to some extent, which has been a bit frustrating for him, but 
I think now we're planning to have more regular FROST meetings, we can 
show what he's achieved so far, clear up some of the issues he's having, 
and keep him on track.

Thanks again to yourself, and the rest of the FROST group, for 
maintaining an interest in this after all these years, we appreciate it.

Cheers,

Stuart
