Dear Molpro Experts,

I have performed CASPT3 calculations with CASSCF wavefunction as a
reference.
I used following input:

***,PSB3
memory, 450, M
SET, CHARGE=1
gexpec, dm
gdirect
geomtyp=xyz
symmetry,nosym
geometry={

}
basis=roos(3s2p1d/2s1p)
rhf
put, molden, PSB3.scf.molden;
{multi
  rotate, 19.1, 20.1, 0
  rotate, 24.1, 30.1, 0
  occ, 25, 0
  closed, 19, 0
  wf, 44, 1, 0
  state, 3
}
put, molden, PSB3.rasscf.molden;
{rs3, shift=0.1, ipea=0.25
  state, 3
}

Now I would like to know what was the coefficient of the reference
wavefunction (CASSCF)
when I calculated states 1, 2 and 3 with CASPT3 method. I cannot find it in
my
*log file.
In other words, how much of the reference has contrivution to the CASPT3
energy.

Best wishes,
Dawid Grabarek
