Subject: G98: can "CISD" be tested by "STABLE" or "STALE=OPT" ?

Dear all,

    After inputting

    # UCISD/6-31G(d) SCF=Tight Stable

in Gaussian 98 (for workstation), I found that this input is the same as
this one:

    # UHF/6-31G(d) SCF=Tight Stable

That is G98 only calculates HF energy not the CI energy instead. Then it
tests whether the HF (not CI)wavefunction is stable or not. So my question
is: can "CISD" be tested by "STABLE" or "STALE=OPT" ? If yes, what should I
input? Thanks in advance.
