[QE-users] Question on local atomic charge

[Mpayami]

Hi All.

I noticed that the calculated electronic charges on atoms which is done by CALLing "get_locals.f90" in "report_mag.f90" in an SCF cycle are somewhat different from
the values obtained when running "projwfc".
The origin of this difference maybe in taking (?) different "atomic radius", R0, in the two methods over which the charge integration is done; or
using low-density k-mesh and lower values of "nbnd" in SCF calculation.
If the latter is true, then how can one benefit the information provided by "report_mag.f90" ?
Any comments is highly appreciated.

Best regards,
