 Dear All,
    Here's the diagram in .ps form. I'm off home in a minute, but there
 appear some differences in levels. Keith and Tim's diagram is the new
 one that didn't make it to the present IPCC draft. For the other two,
 yours has 0.12 added to it to correct your base period of 1902-80 (can't
 remember your exact dates) to 1961-90. For mine we've used a mean and
 SD calculated by Tim based on April-September average temps from the
 NH Land series north of 20N. 
   As I say only problem is the level - the curves are similar given that
 one is a 40 year and one a 50 year filter. We'll work on this more
 tomorrow.

 Cheers
 Phil
