!

! a given couple of determinant det_1, det_2 being a BETA /BETA DOUBLE excitation with respect to one another

!

! c_1 is supposed to be a scalar quantity, such as state averaged coef of the determinant det_1

! big_array(dim1,dim1,dim1,dim1) is the two-body rdm to be updated in physicist notation

!
|

! orb_bitmask(N_int) is the bitmask for the orbital range, list_orb_reverse(mo_num) is the inverse range of orbitals
