Dear penghua,
awin is the width of the window(=interval) around each point over which you
average the planar average to get the macroscopic average. That is to say,
it should correspond to something like, in Latex-ish math,
f_{mav}(x)=\int_{-awin/2}^{awin/2} f_{pav}(x-x') dx'
where f is your quantity of choice (density, potential etc).
Hope this helps.
Best,
Hande
