According to the Affy literature:
Stat Pair: The number of probe pairs available for this probe set
Stat Pairs Used: the number of probe pairs used to make a detection call
for a probe set.

The first one can, of course, be found from the cdf file with a little
work. It is that Stat Pairs Used that I cannot figure out how to get.
