 ### Delta Interface
 
-The Delta Interface allows the user to provide the hybridization function directly instead of providing G0_iw. 
-It can be used by setting delta_interface=True when initializing the solver object. 
+The Delta Interface allows the user to provide the hybridization function directly instead of providing G0_iw.
+It can be used by setting delta_interface=True when initializing the solver object.
 When calling the solver, the quadratic part of the local Hamiltonian must be provided with the parameter h_loc0, which is a many body operator like h_int.
-The Solver.G0_iw and Solver.Delta_infty objects cannot be accessed while using the Delta Interface.
