:term:`LOCAL_WEAKP ` """""""""""""""""""""""""""""""""""""""""""" Desired treatment of "weak pairs" in the local-CIS method. A value of// ``NEGLECT`` ignores weak pairs entirely. A value of ``NONE`` treats weak pairs in// the same manner as strong pairs. A value of MP2 uses second-order perturbation// theory to correct the local-CIS energy computed with weak pairs ignored. * **Type**: string * **Possible Values**: MP2, NEGLECT, NONE * **Default**: MP2
