</span>Yes, plot_num=0 is the correct valence pseudo-charge density.<br>

<br>
</span>That depends on how many electrons your pseudopotentials represent. 7<br>
for Cl sounds about right unless you are doing pretty hardcore stuff<br>
(pun intended). But you shouldn't take my word for it - you can get<br>
the ZPSP by summing the number of valence electrons in the first few<br>
lines of the UPF file (column "occ").<br>

<br>
</span>Your second input should be:<br>
<br>
crystal rho_with_core.cube<br>
load rho_with_core.cube id rhoae<br>
load rho_without_core.cube id rhoval<br>
integrable rhoval<br>
yt<br>
<br>
The point is that you want to integrate rho_without_core (which sums<br>
to the correct number of electrons) in the basins of rho_with_core<br>
(which has maxima at the nuclear positions). Also, if you are using<br>
PAW and a recent version of QE (6.x), you don't need this convoluted<br>
process - a more "correct" version of the rho_with_core.cube can be<br>
obtained with plot_num = 21.<br>
<br>
Best,<br>
