[Pw_forum] How to get average electrostatic potential?

[Yue-Wen Fang]

Dear pwscf users,

I have got electrostatic potential, but I want to average the data to make
the curve more smoothly like FIG11 in this paper
http://prb.aps.org/abstract/PRB/v71/i23/e235317. But I haven't found
correct definition of average electrostatic potential from web of science
up till now. The problem has also troubled me for several days. I put the
data of electric potential alone Z in the attachments. If the data was
plotted, it would to be a curve like many waves, but I want to get a
average one.

Any suggestion is appreciated.
Thank you in advance.
