Masked array seems definitely to be the way to go, thanks a lot.
I must say that this entire issue doesn't make much sense to me: my understanding is the a NaN is different from an INF, therefore one would assume that really there is no reason why a not-number should not be ignored by default by all the array manipulating functions.
Strictly speaking, it should be propagated, i.e., the sum and average should be NaNs also. I don't know why that didn't happen. Chuck
