`refs`

Description: provide saved reference names
Recommendation: refer to sample input for details

`active`

Description: specify single site active orbitals
Datatype: set<int>

`hf`

Description: multisite restricted Hartree-Fock calculation options
Default: use the same options as single site Hartree–Fock calculations

`localization`
