Dear Giovanni
I've found this one into the psl-1.0.0 library.

Are there two different PPs with the same name out there?

Dear Bruce,
if I'm not wrong you're using this pseudopotential:
http://pseudopotentials.quantum-espresso.org/upf_files/Ca.pbe-spn-rrkjus_psl.1.0.0.UPF
If you look inside you see that it has been generate with this valence
configuration:
nl pn l occ Rcut Rcut US E pseu
3S 1 0 2.00 1.200 1.300 -3.461142
4S 2 0 2.00 1.200 1.300 -0.276804
3P 2 1 6.00 1.400 1.600 -2.058527
4P 3 1 0.00 1.400 1.600 -0.103085
As such, when you try to project a band structure of a system containing
this atom, it will only be able to project on 3S, 4S, 3P and 4P states.
You may also check this by looking, inside the UPF file, for the string
PP_GIPAW_ORBITAL
After lines such that
<PP_GIPAW_ORBITAL.1 index="1" label="3S" l="0"
cutoff_radius="0.000000000000e0" ultrasoft_cutoff_radius="0.000000000000e0">
you find the radial part of the corresponding atomic wfc to be used for the
projection. Therefore, if an orbital is not included, the code does not
have access to the radial part of the wfc and will not be able to make any
projection.

Dear QE users and developers,
I am currently working on calculating the projected band structure of CaC6
using quantum espresso with GGA+UItrasoft pseudopotential (
Ca.pbe-spn-rrkjus_psl.1.0.0.UPF). However, I have encountered an issue
with obtaining the 3d orbital wavefunctions for Calcium.
I followed the QE PP examples, and I have managed to obtain the 4s and 3p
orbitals. The 3d orbital was missing while it should existed.
I would greatly appreciate any guidance on how to retrieve the 3d orbital
character of Calcium for my projected band structure calculations.
Thank you for your time and assistance.
Regards,
Bruce
