difference in NGsBlkXs, NGsBlkXp, NGsBlkXd

Dear All,
When I type in the command "yambo -g n -p p", I will get the input name of "NGsBlkXp= 1 RL # [Xp] Response block size". However, sometimes I get difference input names, say, NGsBlkXs or NGsBlkXd, for the same purpose. I am confused but cannot find the relevant explanation about that. Could anyone explain to me about the difference in the meaning of these three names (NGsBlkXp, NGsBlkXd,NGsBlkXs)?

Thanks a lot!
Jianjun

Dear JianJun,
as you said, all the variables have the same purpose, but the name
of the variable depend on the kind of calculation you want to run.
The las letter stands for:
s = static (eps-1 is calculated for omega=0 only)
d= dynamic (eps-1 full dynamic)
p= plasmon pole (eps-1 at omega=0 and imaginary plasmon frequency).

Hope now it is clear,

Cheers,

Daniele
