[Pw_forum] The definition of rho0 in pp's generation？

[Yue-Wen Fang]

Dear all,

What's the definition of rho0 in pp's generation using ld1.x?
Input File Description of ld1.x tells us that rho0 is the charge at the*origin
* when using the Rabe-Rappe-Kaxiras-Joannopoulos method.
But i still cannot figure it out clearly, how to understand *origin*?

Thank you!
