Dear Everyone,
     I'm trying to complete my process of generating the Cesium PP
(extremely hard for a total new and have no experience with QE like me!!!).
So far I have been helped with many other issues, and I'm very much getting
there. I still have couple more questions and hope you can spare me some
time to help me out. my questions are :
 -------the number of logarithmic derivatives to be calculated, the "nld"
value, how does it determine?
--------Angular momentum of the local channel, the "lloc" value, how does it
determine?
 my atom is : Cs with electron config. [Xe] 6s1, and i'm doing ultra-soft
PP. I have checked and it does have the bound state on the p orbital. so I
guess my electron config. should be "[Xe] 6s1 6p-1 ".

I appreciate any input you have for me!
