The message
from Roger contains these words:

I might manage to post as early as tomorrow. OTOH I might not. :-)

Or even today. Figures below are for the unsmoothed annual anomaly from
1850 to 2007. I also have the figures for the smoothed curve if anyone
is interested. I used them and the smoothing filter to check for
extraction errors. I think most of the figures are accurate to 0.01 but
I suspect there may be some minor distortion in the graph which might
make matters worse.

The smoothed curve and my smoothing exercise have a reasonable fit with
only 5 years differing by 0.01 or more. (1850 - 0.023,1851 - 0.14, 1955
& 1956 - 0.01 opposite signs), 2007 - 0.014).

Over to you Terry.
