[esa-t474] Another Paper Update

[Mark Slater]

Dear All,

	First, apologies for this update being a day late - I lost a day 
last week through illness and wanted to get some more finished before 
submitting. Anyway, the latest update contains major overhauls on the 
first and second sections, including many of the comments I've already 
recieved. Still several to go, but I think I'm getting there :)

Thanks,

Mark

P.S. As always, you can find the paper at:
