<DIV><FONT face=Arial size=2>Measure accross the widest part of the
dish (major axis), that was the idea in suggesting a corner to corner
measurement. As long as you measure through the centre the maths will work
out. You should get the same resullt no matter where you measure the dish
although picking the widest point will yield the largest numbers and minimise
the effect of any errors.</FONT></DIV>
