"Natural order" for common mode correction in pnCCD ndarray

pnCCD image has intensity "strips" in both dimensions;


[4][512][512] array averaged over 3 and 1000 events:

At large number of events common mode should be averaged out. For 1000 events horizontal intensity "stripes" have gone.

This proves that common mode should be evaluated for horizontal stripes.
