Dear PWSCF Users.
I want to plot 2D charge density by pp.x and plotrho.x.
In the input file for pp.x for charge density calculation, what is
the unit of e1, e2, which specifies the plotting area of charge density ?
Do e1 and e2 have Bohr length (au) or the unit of alat ?
Is the results of plotting charge has e1 * e2 length^{2} ?
&inputpp
prefic = 'testSample'
outdir = './'
filplot = 'testSample'
plot_num = 0
/
&plot
nfile = 1
filepp(1)='testSamplecharge'
weight = 2
iflag = 2
output_format=2
fileout = 'testSampe.rho.dat'
e1(1)=0.0,e1(2)=1.0,e1(3)=0.0,
e2(1)=0.0,e2(2)=0.0,e2(3)=0.0
x0(1) = 0.0, x0(2)=0.0,x0(3)=0.0
nx = 56, ny = 56
