Hi,

 I've searched through the archive for a response to this question, but I 
can't
seem to find one. I've found one person who asked the same question in 2003,
but it seems to have never been answered. 

Anyways, my question is about rhog, the Fourier components of rhor. I've been
able to print out rhog by adding a line of code to one of the outscf
subroutines. I've checked that the g=zero component (the component
corresponding to index=1) gives the average electronic number density, but I'm
a little confused as to the other components. In a general system (without
inversion point?) rhog should be complex, but in ABINIT rhog looks to be a
real. How is this possible?

Also, is there a way to get rhog output from ABINIT without modifying the 
code?
As an option for prtden card? I didn't think so, but maybe it is a secret.

Also, I am confused about the indexing of rhog. Originally I would have 
thought
that the indexing of rhog works the same as for rhor, but in reciprocal
space... but since the rhog variable is real and not complex in ABINIT I'm not
sure if this is the case... Has anyone else looked into this or is anyone able
to offer advice? thanks in advance.
