13. Success! I would crack open a bottle of bubbly but it's
only 11.25am. The program norwichcorr.for found a correlation
for the norwich series at (363, 286) of 1.00! So we have
found the published Norwich series in the grids I produced. A
palpable sense of relief pervades the office :-) It's also the
grid reference given by Tim for Norwich. So how did I miss it
earlier??
