[molpro-user] basis set of Ce ECP47MHF

[lydia]

Dear all,
In molpro basis set library, there are some basis sets "ECP46MHF,
ECP47MHF, ECP48MHF" for Ce. According to the manule, the "n"  is the
number of core electrons
 which are replaced by the pseudopotential.
 In Ce, the valence electrons are "4f15d16s2".
 The first 46 core electrons are "1s22s22p63s23p63d104s24p64d10",
which is the core electrons in  ECP46MHF.
 The first 46 electrons plus "5s1" are the core electrons for ECP47MHF.
 The first 46 electrons plus "5s2" are the core electrons for ECP48MHF.
Am I right?
 If I am right, I do not understand how to consider "5s1" to the core
potential for ECP47MHF since the two electrons in 5s are so related.
 Or the core electrons for ECP47MHF includes the first 46 electrons plus 4f1?
I am not clear with this. I will be appreciate if you can give me some clues.

Thanks,
