[molpro-user] LCC2 population analysis

The CC2 density on file is just a correlation density from CC2 calculation,
i.e. without the HF density.
If you want to add the HF density, you can do it in matrop:
BTW, you don't need to write "singlet=1" (default), "startle=1", "trans=1",
and "expec,dm" (not relevant) in the case of lt-df-lcc2.
