[molpro-user] About non-HF orbitals used in CCSD(T) calculation

[Chen Hui]

Dear Molpro users,
I have two questions concerning the use of non-HF orbitals in CCSD(T) 
and CCSD(T)-F12 calculations.
The first question is if it is possible in MOLPRO2009 to use non-HF 
orbital (DFT orbital for example) in UCCSD(T) calculation,
since there are this kind of practices for transition metal containing 
systems. I know generally it is of no problem for coupled
cluster calculation to use non-HF orbital, but my question is if MOLPRO 
also permit this. In manual I fail to get information about this.

My second question is that if it is possible in MOLPRO2009  to use 
non-HF orbital in UCCSD(T)-F12 calculation. In manual, I noticed
a sentence read "The MP2-F12, CCSD-F12, and UCCSD-F12 methods must use 
conventional (non-density fitted) spin-restricted Hartree-Fock
reference functions (HF or RHF)." in part 30.1. Does this mean that only 
HF orbital could be used?

Thank you for your answer of my questions above.
