Dear all,

First of all, happy new year!

I am trying to understand the details of Co psp from QE
(http://www.quantum-espresso.org/pseudo/1.3/html/Co.html). In specific, I
have interests in following psps:

Co.rel-pz-n-rrkjus.UPF
(http://www.quantum-espresso.org/pseudo/1.3/UPF/Co.rel-pz-n-rrkjus.UPF) 
Co.pbe-nd-rrkjus.UPF
(http://www.quantum-espresso.org/pseudo/1.3/UPF/Co.pbe-nd-rrkjus.UPF)

In their <PP_INFO>, can anyone explain me why we have multiple lines 4s, 4p,
and 3d sometimes identical occ but sometimes different occ (see below (after
++++) for more details)? I expect that these are related to nonlinear core
correction, I am not so sure
 Your help will “truly” be appreciated. 

Sincerely,

Chan-Woo
