D2 diagnostic in CC2

[evgeniy]

Hello everybody,

Just a short question: the D2 diagnostic for CC2 doesn't seem to be
calculated by default. How can one switch its evaluation on? Thanks!

Best,

it requires that the flag $D2-diagnostic is set in combination with calculation of ground state properties (or a ground state gradient), see remark in the respective section of the manual.

Hello,

Is it possible to obtain D2 diagnostic at CCSD (not just CC2)þ level?
It does not seem to be printed even if I put the `$D2-diagnostic' keyword in my control file.

best regards, M.R.
