- a converged SCF calculation with the one-electron density
threshold set to
`$denconv``1.d-5`

or less - an auxiliary basis defined in the data group
`$cbas` - if orbitals should be excluded from the correlation treatment
the data group
`$freeze`has to be set - the maximum core memory which the program is allowed to
allocate should be defined in the data group
`$maxcor`; the recommended value is 66-75% of the available (physical) core memory. - the data group
`$ricc2`with a specification of the coupled-cluster model

- the data group
`$rir12`with the definition of the standard approximations for the explicitly-correlated contributions (see Sec. 8.5 for details) - the data group
`$lcg`, which define the correlation function (here it is in particular important to choose for F12 calculations the exponent; recommended values are 0.9 for cc-pVDZ-F12, 1.0 for cc-pVTZ-F12 and 1.1 for cc-pVQZ-F12 basis sets) - a complementary auxiliary (CABS) basis set
