Hi Padmaja, I think that in general it cannot be said that a PP is good or bad looking just at the value you mention of AE-PS. Maybe you can try testing your PP in some system in which you know the answer, for instance calculate the band structure of bulk Cr and compare with known results. I see that in the repository of QE PP there are a couple of scalar-relativistic Cr PP's, you can check if their band structures match with yours (with lspinorb=.false. in the case of your fully relat PP). Also you can try to compare this band structure with some all-electron band structure. And finally, it is very good to compare the lattice parameter obtained with your PP in bulk Cr with the real value, I think they should differ at most in 5%. Hope this helps,
